Well, there's no need to use boost::function0<void> I suppose, since
that's easily emulated with a smart pointer to an appropriate abstract
base class.  Given a suitable templated invocation function I think
we could even get it to accept the same range of nullary function
objects that boost::function0<void> accepts, and there would never be
any need to use boost::ref on it for optimization purposes because of
the nature of the call.

Maybe I should do the factorization and put it in the sandbox or
boost::detail...

What about it?
