That doesn't look like it would compile.  signals2::slot objects aren't 
equality comparable because boost::function objects aren't.  I don't believe 
the function objects returned by bind are either.  The best workaround would 
be to not use disconnect-by-slot at all and use the connection object 
returned by the connect call to disconnect.
