Compiling together is faster anyway this is prolly what you want 
most the time.

But I know what's going on now, it is the template emission 
thing, the compiler thinks, since it is from std, it was already 
compiled somewhere else and skips it but it isn't actually there 
so the linker errors.

Using

gdc -fall-instantiations -c parser.d

Might generate it in that parser.o getting it to link. Might need 
to be used in all builds but I *think* just here, hard to say 
without a test.
