I have a hunch that it would be really easy to add support for move-only types, though. Do you see any specific obstacles?
I had a quick try at implementing move-only types. It looks like you're right: http://svn.boost.org/trac/boost/changeset/46631 y.hpp contains the move-only type. The code might look familiar. It mostly works. I've found two problems so far. Firstly, is_convertible didn't work for the type, but I managed to work around that (I'll probably need to refine the change to is_movable). Secondly, it doesn't seem to be able to pass rvalues by reference. I'm not sure how to get round that, I'll have to learn more about the trick used to implement it. Daniel
