Thanks Peter, I think I understand how it works now.  Unfortunately, the
lack of SFINAE is a real showstopper for me.  I want to write functions
like

template <typename T>
typename result_of<negate(T)>::type
operator-(T const& x)
{
   return negate()(x);
}

but the lack of SFINAE here makes boost::result_of essentially useless for
this.  But I imagine it won't be difficult to make a new version based on
boost that would work.

Cheers,
Ian
