I think that there are no blocking problems with this, if you rearrange stuff 
enough it works (I can't prove this but I haven't ever failed to make things 
work)

As to c++ being more flexible than D, some things might take a bit of work 
(like what you are looking at), but in all but the most trivial cases c++ 
can't even hold a candle to D.

OTOH this runs, or am I changing something?
