I have been looking at some of the optimizations, and I found a few interesting differences.
*** Chez may reorder expressions. (car (list (display 1) (display 2))) ;==> 21#<void> I think this is ok in RNRS and Chez, but it may cuase a problem for a program translated directly from Racket. I think that all the reorders are in the optimization phase, but I'm not sure. *** Chez has only one vector of length 0 (eq? (vector) (make-vector (* 0 (random 7)))) ; ==> #t This is not an optimization, but a property of the internal system. I actually like it. It's not very useful for vectors, but it looks like a something useful for strings. (eq? (string) "") ; ==> #t I think that this is one of the small details that have to be fixed, but the change looks like a good idea for Racket2. [But the extended version of (eq? (vector) (vector-immutable)) is something that I prefer to keep #f.] Gustavo -- You received this message because you are subscribed to the Google Groups "Racket Developers" group.
