mixin(import("myCode.d"));

Even better because it doesn't have to output the program at 
runtime, the generated executable *is* the compiled code ;). I 
guess that's just the same as #include though....

If you want to compile to other languages, just use the above 
with ldc --output-ll or --output-bc, then get an llvm decompiler 
to get that to your target language :)

A C compiler using ctfe, now that would take some more work.
