It is actually even worse, as omitting runtime cripples core 
language noticably. I was hinted with this cool project though :

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.
