WebJul 11, 2004 · To understand continuations, it helps to think in terms of continuation-passing style, in which all procedures take an extra parameter, their continuation. In this model, the only difference between a first-class lexical closure, and a first-class continuation, is that when applied, the latter discards its continuation parameter.

WebIn Scheme, the current continuation can be reified as a function by using the built-in function call-with-current-continuation, or call/cc for short.
