currently this code:

void main() {
int[] emptyArray = [];
}



Produces:

__Dmain comdat
L0: pushEAX
mov EAX,offset FLAT:_D11TypeInfo_Ai6__initZ
push0
pushEAX
callnear ptr __d_arrayliteralTX
add ESP,8
xor EAX,EAX
pop ECX
ret

No!

Often it is extremely useful to distinguish an empty array from a null one.
(You do that with is null).

Fixing this will break a lot of my code.

Erm, never mind, [] still creates a null array. I just remembered I had to do
something more tricky in my code to make empty non-null arrays.
