I don't know if I did something wrong or not, but this seems strange to me.
Using #lang racket, in the interaction window from DrRacket (DrRacket, version 5.0.1, english by PLT), > (struct posn (x y)) > (struct? (posn 3 4)) #f > (struct-info? (posn 3 4)) #f #t > So (posn 3 4) is not a struct in racket? The same goes for define-struct. But > (struct-constructor-procedure? posn) #t > Usually how people define structure in Racket? Cheers, Frodo
