Really? I have not had any issues before automatically creating C 
bindings for D using codegen. Sure, occasionally a macro will 
bite but it isn't that often nor difficult to fix.  They were not 
the kernel but they were not small code bases without macros 
either.

TBH though now I just use dpp so I don't see the value of bolting 
on a "C" parser to the D front end. C++ I have struggled with 
that and it requires an annoying amount of manual editing. DPP 
works well but even it falls over for some C++ code bases I've 
tried.
