I'm not sure what this library would be useful for, as we already have _two_
bind implementations (Boost.Bind and Boost.Lambda), both with closure
capabilities. Boost.Bind even works on all compilers around, including the
cranky VC6. I understand that it solves the posted example quite nice, but I
reckon that, in real life, it could have been written to avoid the (ugly
imo) pointer to member function, just using the bind/function facilities,
and with increased genericity too. My view is that Boost should minimize the
slightly-different-libraries-with-overlapping-features syndrome.

On the other hand, I agree that an extension to shared_ptr that correctly
oveloads the ->* operator as shown might be handy.
