#8712: [function] Comparison with nullptr differs from std::function<>
------------------------------+----------------------
 Reporter:  boost@…           |      Owner:  dgregor
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  function
  Version:  Boost 1.53.0      |   Severity:  Problem
 Keywords:  nullptr C++11     |
------------------------------+----------------------
 Whether or not boost::function<> ''should'' support comparison with
 (C++11) nullptr is another issue, but at the moment it is inconsistent
 with std::function<>.

 E.g.

 {{{
 boost::function<void ()> bf;
 bool c1 = (bf == nullptr);   // currently false

 std::function<void ()> sf;
 bool c2 = (sf == nullptr);   // true

 assert(c1 == c2);
 }}}

 Tested with g++ 4.6.3 and Visual Studio 2012.
