We chose "iterator_value" et al because we couldn't be sure that
someone wouldn't need to make another concept Q in boost that had its
own, separate notion of an value_type.  If you then had a type X that
fulfilled both the Iterator and Q concepts, how would you specialize
value_type_of?

I would be happy to unify these using Peter's names if we could give
the problem above some thought and resolve it (even if that means
deciding "it's not a problem").
