We discussed this 5 years ago.
AFAICR David Abrahams terminated the discussion tagging this as defect
(http://osdir.com/ml/lib.boost.user/2003-01/msg00153.html)

The trouble I had with ::_1 has a higher severity level than the breakage.
I kindly ask you again to overcome your reluctance.
Put a proper statement about the breaking change into the release notes 
and remove everything from global namespace.  

Also note that it is a good time to change this, since everybody 
ought to switch to std::tr1::bind anyway and boost::bind could be tagged
as deprecated in favor of boost::tr1::bind.
