continuations - Scheme early "short circuit return"? - Stack Overflow

WebSep 15, 2016 · A common use of continuations is in the implementation of control structures for: returning from a function, breaking from a loop, exception handling etc. Most languages (like Java, C++ etc) provide these features as part of the core language. Some languages don't (e.g: Scheme). WebA Scheme implementation is properly tail-recursive if it supports an unbounded number of active tail calls. A call is active if the called procedure may still return. Note that this includes regular returns as well as returns through continuations captured earlier by call-with-current-continuation that are later invoked.

This is why Scheme requires tail-call elimination: it allows a loop to be converted to a recursive call without potentially running out of stack space.
