This code doesn't work.

import std.algorithm, std.traits;
void main()
{
    static int postblit, dtor;

    static struct S2
    {
        this(this){ ++postblit; }
        ~this(){ ++dtor; }
    }
    S2[3] sa21;
    postblit = dtor = 0;
    S2[3] sa22 = move(sa21);
    assert(postblit == 0);  // fails
}
