In that case I think I didn't specify what subsystem of the D 
compiler was not "good enough", I have just shown a performance 
difference. The division was slow, regardless of the cause. This 
is what's important for the final C/D programmer, not if the 
cause is a badly written division routine, or a bad/missing 
optimization stage.

And regarding divisions, currently they are not optimized by dmd 
if divisors are small (like 10) and statically known.
