Hi Steven, I'm looking for a crash I get in my own code with g++4.8.1 (4.5 - 4.7 are ok). Maybe you can help me: - there is a copy_constructible concept, but no moveable. Is it enough to add one on the same model? It looks like you std::forward so I'd say yes. Correct? template<class T = _self>

struct move_constructible :

::boost::mpl::vector, destructible<T> >

{};

I believe that this should work. However, overloading const T& and T&& only works with clang. (It might work with gcc-4.8, if I enable it. When I wrote the code I only had gcc-4.7.).

- If I std::move a copy_constructible any type by accident, what do I get? A copy? A crash?

It should do a copy. I tried hard to make overload resolution behave the same as it would with real references. In Christ, Steven Watanabe
