Yeah, but Haskell is ludicrous. Prelude> let (x, 2) = (1, 3) Prelude> Only non-falsifiable patterns really make sense as the left hand side of an assignment in a language without exceptions, IMO. Otherwise you should use a match/case statement. (Of course, Python does have exceptions...) -- Devin -- https://mail.python.org/mailman/listinfo/python-list
