No, you need to destroy that rvalue.

You'll note that C++ move constructor still require the old 
object to be in a "null" state so that its destruction can 
effectively be a noop.

When a constructor is involved, you create a new object, and need 
to do something with the existing ones.

This is why I was suggesting to recycle the postblit instead as a 
"postmove" constructor.
