control and the performance is always good.
It is actually even worse, as omitting runtime cripples core
language noticably. I was hinted with this cool project though :

In my very simple test, the GC version of my program ran more
than twice
slower than the non GC version. I just cannot accept that kind
of
performance penalty.
Raw performance is kind of achievable if you use own memory pools
for data and limit GC only for language constructs (appending to
slices, delegates etc.) - those to approaches can happily coexist
in D.
Problems start when soft real-time requirements appear.
