Default A error in a library named AutoIndex

Help!This is a library named AutoIndex.
Why run error in

What's mean this statement?

Collapse JASS:
library AutoIndex
//===========================================================================
// Information:
//==============
//
//     AutoIndex is a very simple script to utilize. Just call GetUnitId(unit) to
// get get the unique value assigned to a particular unit. AutoIndex differs from
// other unit indexing libraries because it automatically assigns an ID to each
// unit as it enters the map, and automatically frees that ID as the unit leaves
// the map. This gives you several advantages as the user:
//   -The GetUnitId function inlines directly to a GetUnitUserData call (or a
//    LoadInteger call if the UseUnitUserData constant is set to false.)
//   -You don't need to manually free IDs as units leave the map.
//   -Detecting removing units to free their indexes is O(1), and less costly
//    performance-wise than a timer scanning the map for removed units.
//
//  If you turn on debug mode, AutoIndex will become slower, but it will be able
//  to display several helpful error messages. It can detect the following issues:
//   -Passing a removed or decayed unit to GetUnitId
//   -Code outside of AutoIndex has overwritten a unit's UserData value.
//   -GetUnitId was used on a filtered unit (a unit you don't want indexed).
//
//     AutoIndex uses UnitUserData by default. If something else in your map
// would conflict with that, you can set the UseUnitUserData configuration
// constant to false, and a hashtable will be used instead. Note that hash-
// tables are about 60% slower.
//
//     AutoIndex provides events upon indexing or deindexing units. This
// effectively allows you to notice when units enter or leave the game, and
// handle the creation or destruction of attached data or other things. Also
// included is the AutoStruct module, which automatically creates and destroys
// struct instances associated with units as they enter and leave the game.
//
//===========================================================================
// How to install AutoIndex:
//===========================
//
// 1.) Copy and paste this script into your map.
// 2.) Save it to allow the ObjectMerger macro to generate the "Leave Detect"
//     ability for you. Close and re-open the map. After that, disable the macro
//     to prevent the save delay.
//
//===========================================================================
// How to use AutoIndex:
//=======================
//
//     So you can get a unique integer for each unit, but how do you use that to
// attach data to a unit? GetUnitId will always return a number in the range of
// 1-8190. This means it can be used as an array index, as demonstrated below:
/*
    globals
        integer array IntegerData
        real array RealData
        SomeStruct array SomeStructData
    englobals

    function Example takes nothing returns nothing
        local unit u = CreateUnit(...)
        local integer id = GetUnitId(u)
            //You now have a unique index for the unit, so you can
            //attach or retrieve data about the unit using arrays.
            set IntegerData[id] = 5
            set RealData[id] = 25.0
            set SomeStructData[id] = SomeStruct.create()
            //If you have access to the same unit in another function, you can
            //retrieve the data by using GetUnitId() and reading the arrays.
    endfunction
*/
//     The UnitFilter function in the configuration section is provided so that
// you can make AutoIndex completely ignore certain unit-types. Ignored units
// won't be indexed or fire indexed/deindexed events. You may want to filter out
// dummy casters or system-private units, especially ones that use UnitUserData
// internally. xe dummy units are automatically filtered.
//
//===========================================================================
// How to use OnUnitIndexed / OnUnitDeindexed:
//=============================================
//
//     AutoIndex will fire the OnUnitIndexed event when a unit enters the map,
// and the OnUnitDeindexed event when a unit leaves the map. Functions used
// as events must take a unit and return nothing. An example is given below:
/*
    function UnitEntersMap takes unit u returns nothing
        call BJDebugMsg(GetUnitName(u)+" was indexed with the ID "+I2S(GetUnitId(u)))
    endfunction

    function UnitLeavesMap takes unit u returns nothing
        call BJDebugMsg(GetUnitName(u)+" was deindexed with the ID "+I2S(GetUnitId(u)))
    endfunction

    function Init takes nothing returns nothing
        call OnUnitIndexed(UnitEntersMap)
        call OnUnitDeindexed(UnitLeavesMap)
    endfunction
*/
//     As you can see, it works perfectly fine to call GetUnitId() on a unit
// during either of these events.
//
//     If you call OnUnitIndexed during map initialization, every existing
// unit will be considered as entering the map. This saves you from needing
// to manually enumerate preplaced units (or units created by initialization
// code that ran before OnUnitIndexed was called).
//
//     OnUnitDeindexed runs while a unit still exists, which means you can
// still do things such as destroy special effects attached to the unit.
// The unit will cease to exist immediately after the event is over.
//
//===========================================================================
// AutoIndex API:
//================
//
// GetUnitId(unit) -> integer
//   This function returns a unique ID in the range of 1-8190 for the
//   specified unit. Ruturns 0 if a null unit was passed. This function
//   inlines directly to GetUnitUserData or LoadInteger if debug mode
//   is disabled. If debug mode is enabled, this function will print
//   an error message when passed a decayed or filtered unit.
//
// OnUnitIndexed(IndexFunc)
//   This function accepts an IndexFunc, which must take a unit and
//   return nothing. The IndexFunc will be fired instantly whenever
//   a unit enters the map. You may use GetUnitId on the unit. When
//   you call this function during map initialization, every existing
//   unit will be considered as entering the map.
//
// OnUnitDeindexed(IndexFunc)
//   Same as above, but runs whenever a unit is leaving the map. When
//   this event runs, the unit still exists, but it will cease to exist
//   as soon as the event ends. You may use GetUnitId on the unit.
//
//===========================================================================
// How to use the AutoStruct module:
//===================================
//
//     The AutoStruct module allows you to automatically create and destroy
// struct instances as units enter and leave the game. An instance of the
// implementing struct will be created each time a unit enters the game,
// and destroyed when that unit leaves the game. (You cannot create or dest-
// roy instances manually.) This means that you should consider each inst-
// ance of an AutoStruct to be "owned by" a specific unit.
//
//   AutoStruct restrictions:
//   -You may not implement AutoStruct in any struct that declares its
//    own create, destroy, or operator[] methods.
//
//   -You may not manually create or destroy structs implementing AutoStruct.
//    Creation and destruction are handled automatically as units enter/leave.
//
//   -AutoStruct may be implemented in structs that extend interfaces or
//    other structs, but only if the allocate() method takes no parameters.
//    (The restriction of allocate() taking no parameters may be changed soon.)
//
//   -AutoStruct will not work with structs that extend array, since they
//    can't be created or destroyed.
//
//  AutoStruct features:
//   -An instance of the implementing struct will be created each time a
//    unit enters the game. That instance will be destroyed when that unit
//    leaves the game. The struct will always exist while the unit does.
//
//   -You can retrieve an AutoStruct from a unit by using the syntax:
//      local StructName mystruct = StructName[unit]
//      //This inlines to a GetUnitId() call + array lookup.
//
//   -You can refer to the unit that owns the instance by the member "me":
//      //Outside of the struct:  call BJDebugMsg(GetUnitName(mystruct.me))
//      //From within the struct: call BJDebugMsg(GetUnitName(me))
//
//   -You can use the optional methods onCreate and onDestroy to notice when
//    instances of a struct implementing AutoStruct are created and destroyed.
//    This is equivalent to detecting a unit entering and leaving the game.
/*
        struct Example
            private method onCreate takes nothing returns nothing
                call BJDebugMsg(GetUnitName(me)+" has entered the game!")
            endmethod
            private method onDestroy takes nothing returns nothing
                call BJDebugMsg(GetUnitName(me)+" has left the game!")
            endmethod
            implement AutoStruct
        endstruct
*/
//   -You can filter which units will recieve an AutoStruct by using the
//    optional static method createFilter. The createFiler method must take
//    a unit parameter and return a boolean (true if created, false if not).
/*
        struct Example
            private static method createFiler takes unit u returns boolean
                return GetUnitTypeId(u) == 'hfoo' //Only Footmen will recieve this AutoStruct.
            endmethod
            implement AutoStruct
        endstruct

//map. Disable it by removing the exclamation to remove the delay while saving.
