RE: Keywords in GOOPS methods

>Well, these particular examples aren't valid since GOOPS doesn't allow type specifiers for keyword arguments. (It's the same in CLOS.) Type dispatch is done *only* on the required arguments.

That’s a shame, it should support them IMO, it’s a major limitation if it doesn’t.

A variant with untyped keyword arguments:

(define-method (f (a <keyword>) (b <symbol>))
  (pk 'positional))

(define-method (f (#:key foo))
  (pk 'optional-keyword foo))

(f #:foo 'bar)

Who should win? Both are a quite specific match.
