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.
