Questions tagged [continuations]
In computer science and programming, a continuation is an abstract representation of the control state. A continuation reifies an instance of a computational process at a given point in the process's execution. It contains information such as the process's current stack (including all data whose lifetime is within the process e.g. "local variables"), as well the process's point in the computation.
