Unless I'm being dense, (x y) isn't a valid single match pattern? [Quasipatterns like `(x y) or `(,x ,y) would be.] But even if it is grammatically possible, like I said at the end, I'm not sure it's worthwhile. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
