Continuation koans

Zen Panda from Airy Nothing.

Callcc is the ultimate control structure, but it requires some getting used to. Continuation koans will help you meditate callcc to expand your awareness.

As far as I know the only mainstream languages in which callcc is available are Ruby and Scheme (and maybe Smalltalk). There was once Python fork (Stackless Python) with callcc, but it's dead. And there is some talk about adding callcc to Perl 6, but we all know it's Duke Nukem Forever of programming languages ;-)
