Except it isn't.

move memcopy T.init . So it will be null.

Try it. Without a destructor, move does not revert to T.init. With a destructor you get this:

src\phobos\std\algorithm.d(1564): Error: variable std.algorithm.move!(NotNull!(int*)).move.empty initializer required for type NotNull!(int*) Error: template instance std.algorithm.move!(NotNull!(int*)) error instantiating

This is what @disable this does, and what it's supposed to do.

Ho that is awesome !

Still many way of generating it on the heap, but it seems that the stack is getting better !

Hm. The heap. That should be new NotNull!(int*), and
(new NotNull!(int*)[1])[0]. The former is correctly not allowed, and the
latter is a different manifestation of the same bug mentioned previously.

Of course, with casts and pointers, anything is possible.
