I had been thinking about that as well. My personal implementation looks
alot like:
a) Add a new type_trait called moveable.
b) Add a function called move_wrap, where you construct objects you want
to move like:
Class b, c=move_wrap(d);
b=move_wrap(c);
Where move_wrap passes it's parameter straight through if the type_trait
moveable is false, and wraps it in a class called MoveWrap if moveable
is true (which can then be used in the constructors of Class).
The advantage of just writing a swapping library is that it isn't going
to involve adding new constructors / destructors based on a
templated-based implementation of moveable, which might be incompatable
with other people's definition of moveable.
