[Chicken-users] Continuations, control flow, and F-operator
... So, how does F-operator even exist? It's an egg that implements delimited continuations, that much I know, but HOW? IIRC, it's only possible to implement delimited continuations in pure scheme if all control flow is implemented in continuations. So is that what chicken does? I mean, I know call/cc is fast in chicken, but is it that fast, or is F-operator using some chicken specific implementation that I don't know about? ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users

Calling an escape procedure from call/cc is as fast in Chicken as calling a "normal" procedure (which is to say somewhat slower than in comparable Schemes like Gambit), so Oleg Kiselyov's portable implementation works well. There are only a few Chicken-specific touches, as you can see by loading the code with "chicken-install -r F-operator". -- John Cowan http://www.ccil.org/~cowanco...@ccil.org By Elbereth and Luthien the Fair, you shall have neither the Ring nor me! --Frodo ___ Chicken-users mailing list Chicken-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/chicken-users
