I would question whether that should be a method of Pair at all,
since it's not the length of the pair itself, but the length of
a structure built out of pairs.
But in any case, the way to do this in a conceptually clean way
is for the length method of Stack to call whatever it is that
computes the length of a linked list of Pairs. This is what
the term "delegation" refers to.
