How on earth would you do:
char GenCode(T)(char name)
return T.stringof ~ " " ~ name ~ ";";
Across the program execution boundary? How do you pass that template param?
Your CodeGen program can only take char, remember.
(This is a simple example which could be done with templates too, but
imagine this function is much longer.)
Multiple compilations sounds like a terrible hack, and isn't nearly as
simple or expressive as this.
