//  For backward compatibility, this header includes
//  <boost/bind/bind.hpp> and then imports the placeholders _1, _2,
//  _3, ... into the global namespace. Definitions in the global
//  namespace are not a good practice and this use is deprecated.
//  Please switch to including <boost/bind/bind.hpp> directly,
//  adding the using directive locally where appropriate.
//  Alternatively, the existing behavior may be preserved by defining
//  the macro BOOST_BIND_GLOBAL_PLACEHOLDERS.
