D has better way to bind to C++ than to D.

Yeah, we're supposed to define or generate a header module that 
has the same name as the real module. It can probably be also 
accomplished with some really ugly `pragma(mangle, "...")` 
trickery, but I agree that defining module names in `extern(D)` 
would be much nicer and sometimes a better solution than a header 
file for every linked-to source file. D ABI should be just as 
practical for separate compilation as C and C++ ABIs.
