Well technically it was that much faster because it did optimize
away the useless calcOn Tuesday, 12 February 2013 at 23:31:17

Brilliant! Yes, that is why the time was coming out to be
zero, regardless of
what value of DIM I put. Thank you very very much.
LOL. For a while you thought that C++ could be that much faster
than D? :D
Well technically it's not that C++ is faster than D or
visa-versa, it's that the two compilers did different
optimizations, and in this case one of the optimizations that g++
did (removing redundancies) had a large effect on the outcome.
It's entirely possible that DMD can still beat g++ under
different circumstances.
