I don't know what 'bind' does exactly, but the mechanism would have to handle
the regular pointer-to-data-member case also.  Overloading won't work, because a
general T::* would catch everything--including the pointers-to-member-functions.
The sample that I sent hijacks that with a specialized closure for that purpose
only.  That was the purpose of the closure<U>::return_type typedef.
