I know that 'bind' (now in std::tr1) will bind pointers to member functions to smart 
pointers.  But is there a simple way to bind to a "weak" pointer, such that the attempted 
call will realize the smart pointer and if successful perform the call, or if unsuccessful 
just not call anything without complaint?  (In this case, it appears that the return is void)
