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