Oh, I see I missed the call to local-expand in the loop, sorry. But what is this supposed to do at the REPL? DrRacket and Racket at least agree, but it isn't what I would have predicted: > (begin (define begin +) (begin 1 2)) . begin: function application is not allowed; no #%app syntax transformer is bound in: (begin 1 2) Are they doing the right thing? (Inside a module we get the expected 3.) Robby _________________________ Racket Developers list: http://lists.racket-lang.org/dev
