Hmm, maybe I just found out. If B is an S4 subclass of A (aka extends
A), how does B's method foo invoke A's foo?
The question assumes that A's foo was defined as an in place function,
so there's no (obvious) named object for it, i.e,
setMethod("A", signature(blah="numeric"), function(x) something)
