I was already suspecting that struct: must somehow be different from define-struct: in TR, because I had #:property prop:equal+hash working with define-struct: but not with struct: in 5.0.1, but there downloading 5.0.2 fixed the problem :-; In fact it would be great if you could look into it, because the change to struct: is just wonderful from an aesthetic perspective already, it makes the code look so much cleaner (especially with deeply nested structures) :-; BTW having switched to 5.0.2 now, I'm enthusiastic about the performance gains too - the TR code seems to execute much faster now - thanks for that too :-) > > Check out the `racket/load' language for exactly this purpose. Sorry I don't get it - is there a way I could use it to have both struct: and not get the syntax error? I've tried (without really understanding the chapter in the reference, I must admit) #lang racket/load (require rackunit) (require rackunit/text-ui) (require "../types.rkt") (require "../tests/types-test.rkt") but I get the same error ../tests/types-test.rkt:15:23: Triple: illegal use of syntax in: (Triple "count" number? 1) Sigrid _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
