i think that 64-bit gcc/gdc turns sse optimisations on anyway, 'cause
there is no x86_64-capable CPUs without sse. and i'm on x86 arch.

gcc/clang inlines floorf().
gdc generates calls to floor() in both cases, C floor() is just faster.
i.e. gdc fails to see that floor() can be converted t

What is really awesome about this is that his code actually worked, the
mixing of operator overloads, opDispatch and rarely used features(e.g.
comma op).
D has come a long way in the last decade.
