Ok, so my lexing code kinda works, except that commas can also appear  
in instance variables that are function pointers.  And probably other  
wacky c corners that I don't know about.

Anyway, a related question: can I get the start and end source  
location for the instance variable statement, not just the instance  
variable name itself?  E.g., the whole SourceRange of "int a;", not  
just of "a".

Thanks,
