In one sense, this is obviously true, since `andmap` is short-circuiting. But with a sightly different implementation of `andmap`, I think (based on looking at the decompiled output) that these would generate basically identical code. So the extra higher-orderness shouldn't be a performance problem here. Sam _________________________ Racket Developers list: http://lists.racket-lang.org/dev
