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. John
