I see.

I use fixed size arrays all the time in D. Heap-allocated arrays 
are overused in D. They produce garbage and in lot of cases they 
are not needed. Using them a lot is sometimes a bad habit (if you 
are writing script-like programs they are OK), that's also 
encouraged by making them almost second-class citizens in Phobos 
(and druntime, using them as AA keys causes performance troubles).

If you take a look at Ada language you see how much 
static/stack-allocated arrays are used. In high performance code 
they help, and I'd like D programmers and Phobos devs to give 
them a little more consideration.
