You are wrong, it is how the language is meant to behave. Virtualness
is not the problem, name lookup is.

this will hide S::write (ostream &);
you need a using declaration to do what you want.

name lookup only finds T::Write (Output&) as the set of viable
functions within which to do overload resolution.
