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.
Sorry for not catching this yet because I can't find time to fully understand your approach and do some portability tests. Just to make things a bit easier when I have some time, what do you mean with "make copyable types *implicitly* movable"? Can you give me a concrete example of what's possible with your approach that was not possible before? Best, Ion
