A very good explanation. See these two in order: // source: https://en.wikipedia.org/wiki/Call-with-current-continuation https://en.wikipedia.org/wiki/Call-with-current-continuation Criticism: Oleg Kiselyov, author of a delimited continuation implementation for OCaml and designer of an API for delimited stack manipulation for the implementation of control operators, advocates the use of delimited continuations instead of the full-stack continuations that call/cc manipulates: "Offering call/cc as a core control feature in terms of which all other control facilities should be implemented turns out a bad idea. Performance, memory and resource leaks, ease of implementation, ease of use, ease of reasoning all argue against call/cc"[3] Delimited Continuation: https://en.wikipedia.org/wiki/Delimited_continuation https://en.wikipedia.org/wiki/Delimited_continuation
