This compiles since 2.089.1:

void main() {
    import core.atomic;
    {
        shared ulong x = 0x1234_5678_8765_4321;
        atomicStore(x, 0);
        assert(x == 0);
    }
    {
        struct S
        {
            ulong x;
            alias x this;
        }

        shared S s;
        s = 0x1234_5678_8765_4321;
        atomicStore(s, S(0)); // note this is not atomicStore(s, 0);
        assert(s.x == 0);
    }
}

I'm not sure that atomicStore should even try alias this. This can probably be
closed as resolved now.
