Note that [] is a request to the runtime to build an empty array. The
runtime detects this, and rather than consuming a heap allocation to
build nothing, it simply returns a null-pointed array. This is 100% the
right decision, and I don't think anyone would ever convince me (or
Andrei or Walter) otherwise.
Obviously this is the right thing to do !
The question is why an array of length 0 isn't nulled ? It lead to
confusing semantic here, and can keep alive memory that can't be
accessed.
int[] arr;
arr.reserve(10000);
assert(arr.length == 0);
