Technically, the straight up "C - style" syntax also does this 
just as well:

"int[2][] a = new int[2][2];"

Since the last "[2]" gets  rewritten to "[](2)"

But when written that way, I find it is not very clear what 
happens.

Ideally, I wish we could allocate static arrays on the heap 
easily:

"int[2]* p = new int[2]()"

Anybody know why this doesn't work? In a GC language like D, that 
has to track "capacity/usage" of its dynamic arrays, there is a 
real gain to being able to specify: I want my damn array to be 
fixed in size: Don't track any growing information for me.
