What fails is that initialization of the mutable reference on
the left-hand side from the const reference on the right-hand
side.

Ah, right. In D a copy is a move followed by a post-blit and the
move fails because the source is const, got it.
It's still silly, though. In theory the compiler could check the
postblit constructor to see if it copies (I'm aware this might be
easier said than done).
In my case it'll mean that I'll have to drop const off of some
methods because of this. And they really should be const...
I hate to say it, but this is where const_cast would take care of
the problem for me in C++.
