Hi,

I've recently taken a look at the Boost.Move library and it seems that 
it is only possible to make 1) either non-copyable types movable or 2) 
make copyable types move-aware by explicitly moving them.

Now, I've discovered for myself that it is possible for pre-c++09 
compilers to make copyable types *implicitly* movable by detecting 
temporaries that can be moved.

So, my question is whether this is well-known and this feature was 
deliberately excluded from Boost.Move or nobody has discovered it yet.
It would be great to have support for copy- and (implicit) move-semantics.
