there is nothing in the language that provides this functionality
and I would argue that the caller should be able to do such things ...
the object should be in control of the functionality it provides not the user.
hmm, I don't think I explained that very well - I'm having a bit of a
brain freeze ...
if you need to expose parent::foo() via a subclass then you shouldn't
override it in the subclass but rather create a foo2() (for instance)
