Hi everyone! Here is the source code:
(define cc #f) (begin (call/cc (lambda(k) (set! cc k))) (display "Will you catch me?\n")) (cc) In newest Racket, (cc) => nothing In newest Chez/Ypsilon (cc) => Will you catch me?\n I asked an expert about this, and he said that Chez/Ypsilon is right. Then I post a bug report to Racket, Matthew Flatt said [R6RS isn't clear on the point of splicing `begin's or on the continuation of a module body.] Then I checked r7rs-small-draft-9, I believe there is some ambiguity here. What do you think about this problem? Actually I am a Scheme newbie, I apologize if this problem doesn't make any sense.
