Hmm, I see this was discussed before:
http://lists.boost.org/boost-users/2011/07/69621.php

Which I failed to find first time I searched.

There is still the case where I want to prevent copying (but allow 
moving), and boost::noncopyable was what I used before move semantics.

I guess we could have:

    class moveonly
    {
    protected:
       moveonly() = default;
       moveonly(moveonly&&) = default;
       moveonly& operator=(moveonly&&) = default;
       // implicit
       // moveonly(moveonly const&) = delete;
       // moveonly& operator=(moveonly const&) = delete;
    };

So that there is an expressive and concise form of "I want this to have 
default move semantics without being copyable".
