Bind libraries in general have trouble with overloaded functions; this is a 
limitation of C++. boost::bind is slightly better than lambda::bind in such 
cases.

No, there is no list of the differences between boost::bind and 
lambda::bind. FWIW, I wasn't aware of the above difference in behavior, so 
the list wouldn't have had it anyway. :-)
