I have not looked, and to be honest I'm wary of digging through another library just to find something that obviously is already in your head. Could you give a short description of the relevant properties of conversion::assign_to?

It can't. Or at least I don't think that should be the case. move_raw should be strong-typed just like copy assignment and move assignment (with the difference that the underlying type has to be compatible).

That's very interesting. I'll get back on this.
