Signatures are already in there (look in the log in collects/lang) - they're just not documented yet. They already give you this, for example: (define-struct foo (a b)) (define-struct bar (c d)) (define foo-or-bar (signature (mixed foo bar))) At the very least, `define-datatype' should also define a signature. -- Cheers =8-} Mike Friede, Völkerverständigung und überhaupt blabla _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
