That's probably right, for two reasons:

1.  Other than the GC, D doesn't have any "hidden cost" features that 
would explain it being slower than C++ for similarly written code.

2.  A few posts back, it was noted that DMD2.053, which includes my GC 
optimizations, was substantially faster than 2.052, which doesn't.
