Just extend D so that it accepts C code, then macro expansion 
will work. You are 90% there already.

Or rather, extend C so that it accepts D code.

So when you expand $MACRONAME(param) you inject a C-context that 
accepts D  mixed in.

Should work 99.9% of the time. That is good enough, now you only 
have to manually deal with 1 in 1000. 90% is not good enough, as 
that means dealing manually with 1 in 10...
