Marat Abrarov: Does anybody know why functional objects created by means of boost::bind have no move constructors. It would be rather useful especially when such functional objects consist of some smart pointers (like boost::shared_ptr). For example, move constructor of boost::shared_ptr is very light (comparing to its copy constructor) - it doesn't use any CAS at all. May be someone know the reason of move constructor absence or maybe someone know any plans of implementing it.
michi7x7: I wondered about that too. The reason might be the huge ammounts of code that need to be changed within boost::function. However, I'm sure it will come soon.
I mean not boost::function but functors created by boost::bind (boost::bind_t....) - they are rather simple - like tuples, so, I think, their move constructors would be simple too. But it would be great to have move constructors in boost::function too (which is more difficult because of current boost::function implementation). Interesting, what is about std::function (or std::tr1::function) in STL implementations with C++0x support, for example, in STL shipped with MS Visual C++ 2010. Marat Abrarov.
