generic methods and trailing arguments

[Lars J. Aas]

With Goops' generic methods, it seems like trailing arguments are
ignored when method arbitration is done.  Take for instance this
example:

  (define-method (hello arg) (display "1 arg\n"))
  (define-method (hello arg arg2) (display "2 args\n"))

  (hello 1)
  => 1 arg
  (hello 1 2)
  => 2 args
  (hello 1 2 3)
  => 2 args

Is there a way to make the method arbitration more strict?  Maybe
it's a bug?  I'm using the goops 0.9 distribution.
