Introduction and motivation

We start by motivating our interest in continuations. One part of the story is the usefulness of a mechanism that allows us to 'jump out of a deep subexpression'. Another part is the possibility of controlling and manipulating the 'remaining part of the calculation' relative to some given control point.

It is sometimes necessary to escape from a deep expression, for instance in an exceptional case

We are interested in a primitive which allows us to control the remaining part of a calculation - a so-called continuation.

  • Exit or exception mechanism:

    • The need to abandon some deep evaluation

  • Continuation

    • Capturing of continuations

    • Exploring new control mechanisms by use of continuations

Scheme supports first class continuations dressed as functions
