Pointers to C++ Member Functions

Pointers to Member Functions are one of C++'s more rarely used features, and are often not well understood even by experienced developers. This is understandable, as their syntax is necessarily rather clumsy and obscure. While they do not have wide applicability, sometimes member function pointers are useful to solve certain problems, and when they do apply they are often the perfect choice, both for improved performance and to make the code sensible.
