Remember that the "name" of a generic function is a symbol, and the identity
of a symbol consists of both its symbol-name, like "ADD", AND its
symbol-package.  If your two classes are independent, as you say, then
perhaps there is no reason for these two methods to belong to the same
generic function, even though  for  both  the string "ADD" seems like a good
name.  The solution in that case is to name them both "ADD", but in
different packages.
