continuation passing style
PROGRAMMING STYLE
Continuation passing style; CPS conversion; Direct style; Continuation passing; Continuation Passing Style; Continuation-passing
<programming> (CPS) A style of programming in which every user
function f takes an extra argument c known as a continuation.
Whenever f would normally return a result r to its caller, it
instead returns the result of applying the continuation to r.
The continuation thus represents the whole of the rest of the
computation. Some examples:
normal (direct style) --> continuation passing
square x = x * x square x k = k (x*x)
g (square 23) square 23 g
(square 3) + 1 square 3 ( s . s+1 )
