[Rd] Wondering about methods (selecting a less specialized method)

[Byron Ellis]

Hi All,

I find myself wondering if there is a canonical means of achieving the
multiple-dispatch version of 'super'? Specifically, I have a set of
classes

A, B, X and Y where B extends A

and a method Foo with the signature (X,A,Y) and I'd like to implement
Foo with the signature (X,B,Y) such that it calls Foo_(X,A,Y) and then
does "other stuff." This gets a bit complicated with multiple
inheritance but at the moment the best I can think to do is an
explicit call to selectMethod.
