Hmm, I see this was discussed before:
http://listarchives.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".
