I think we just should do those little fixes on D2 (eg. fixing 
the standard library, DIP45), instead of yet again reinventing 
the wheel. We have limited resources, I think first and foremost 
we should port the backend from C to D to further improve our 
productivity on the main compiler, then bugfixes and implementing 
non-x86 targets will be much easier.
