How do you allocate an associative array on the heap?

They are allocated on the heap implicitly; there's no need for
`new`. You actually *can't* use new with an AA, which is what the
compiler is telling you.
void main()
{
alias A = int[string];
A b = []; //No allocation yet, b is null
b["test"] = 1; //b is now non-null
}
