Subject to discussion .... Either seems plausible. What currently
happens is that setMethod constructs a method that contains the
programmer's supplied definition as a local function and calls it
(needed so that argument re-matching can take place).
An advantage of the method not having ... is that errors in naming
arguments are more likely to be caught.
