Yes. In gcc they are replaced with the synthesize method name string  
as well.

Yes. As you pointed out, 'length' of array type is the problem. This  
is not a feature that I have seen used in objective-c. But  
nevertheless....
Either length of array should be ASTized or the entire macro should  
be represented by an 'AST'. This of course has consequences in type  
matching, sizeof, etc. down the road. I will look at this later on.
