I just started learning a bit of Scheme. From what I read Chicken Scheme has very cheap call/cc. Even its domain name is call-cc.org. Is that very rare around Scheme implementations? Currently I'm thinking about Kawa for Android, maybe Bigloo for Windows (.NET) and Gambit for everything else. And I start to wonder how different implementations have different properties even among compiled ones. Edit: a typo: s/Kiwi/Kawa/

Look up LambdaNative.org. It is based on Gambit, and will run on all common platforms. And I think you mean Kawa Scheme, not Kiwi.

  I read about it - it uses Gambit everywhere and draws its own widgets. On Android it has to use JNI. I'm thinking about wxWidgets in Scheme, but with almost none FFI penalty on every platform.

Chicken has free call/cc due to the Cheney on the MTA memory management. This is very rare. Most often it doesn't matter much, since call/cc is rare enougn. I would still prefer delimited continuations since they are easier to reason about. Most often you pick one implementation and stick with it. Scheme is not like CL where you can run the same program on many different implementations without much fuss. Chicken is a very nice implementation with the most friendly IRC channel on freenode.
