Sounds OK to me.  If easy to implement, I'd suggest we allow, but do not
require, the template keyword in this context.

(I'm not sure why the committee decided to allow "template" here; DR
180 notes that "typename" is actually forbidden in this context, i.e.,
that you cannot say:

 template <class T>
 struct C : public typename A<T>::X { };

Hmm.)
