[boost] [function] Bind to std::function if supported?

The boost::move library binds to std::move/T&&/etc. when the compiler supports 
such features, and only uses work-around mechanisms when the compiler lacks 
such support.

Should we add similar support for boost::function?

something like:

#ifdef BOOST_FUNCTION_USE_STANDARD_LIBRARY_FUNCTION
// alternative: #ifndef BOOST_NO_CXX11_HDR_FUNCTIONAL
#include <functional>
namespace boost
{
    using ::std::function;
}
#else
// whatever boost::function currently does
#endif
// ... something similar for boost::bind and std::bind

I haven't looked at boost::atomic yet, but we could also consider similar 
bindings to std::atomic if the library doesn't already do so.
