I wan't aware that `opPostMove` has been implemented as a callback to `move` inside the druntime!

Why hasn't support for dmd been added already?
Lack of time?

I believe that opPostMove was abandoned in favor of move constructors for more or less the same reason that postblits were abandoned in favor of copy constructors (that is, problems with const/immutable).

I'm not sure what the current status of move constructors is.

Ahh. I kind of knew that. Thanks.
