Sorry, hit return inadvertently. Anyway, the idea would be, instead of just
writing:

  const _Functor

writing something like:

  typename conditional<(sizeof...(_Args) >= 0,
                       typename add_const<_Functor>::type,
                       typename add_const<_Functor>::type>::type

I think that should work, it does in some simple tests I did, and all in all,
properly polished, doesn't even look too bad, IMHO.
