At compile time, if an AA is null, then AA.length is zero.

int main()
{
    int[int] w;
    return w.length; // OK
}

But:

static assert({
    int[int] w;
    return w.length;
}()==0);

fails with:
\..\src\druntime\import\object.di(362): Error: _aaLen cannot be interpreted at
compile time, because it has no available source code

Both D1 and D2.
