Most parts of macro preprocessor have already been implemented by vexorian,
the problem is they do not all look like preprocessor constructs.
  • //! include
  • //! external
  • //! textmacro
  • optional
  • static if
  • module

The last three clearly do not look like preprocessing statements but rather like jass extensions.
This kind of programming stile is misleading.

As for comments on the estetics of this stuff vs C preprocessor directives,
I think that should have to wait for someone to make proper color coding for #statements.

It takes some time for people to learn how to use C preprocessing properly.
Here is a tip for your particular problem:
Make a macro for GroupRemoveUnit before you make a macro for RemoveUnit.

You got that the wrong way.
Removing comments has been disabled so preprocessor would not destroy old external commands and textmacros. Compatibility ftw.

Yes they are.
There is an option to turn it off but I see no reason for it.

No, C preprocessing happens before EVERYTHING else.
That way you can do things like this:
Collapse JASS:
ifdef PUI
library mylib uses PUI
elif Autoindex
library mylib uses Autoindex
else
  error "mylib needs at least one indexing system"
endif
Of course optional keyword does the same in one line,
but than again it does not error if you have both libraries at the same time
or if you don't have either.
