Continuations are extremely useful in functional programming languages (e.g. the Cont monad in Haskell) because they allow a simple and regular notation for imperative-style code. They're also useful ...
I am trying to learn continuations and use them to implement coroutines in Scheme. I have two procedures (coroutines) a and b, and I switch between them in the following way: ;; c is a continuation. ...
An interesting discussion about the distinction between callbacks and continuations over on SO has prompted this question. By definition, a continuation is an abstract representation of the logic ...
We all know and love that function calls are usually implemented using the stack; there are frames, return addresses, parameters, the whole lot. However, the stack is an implementation detail: ...
I'm trying to figure out how an open socket or file handle should interact with continuations. Searching has revealed that dynamic-wind is probably part of the solution, but I'm more interested in the ...
The definition of a Y combinator in F# is let rec y f x = f (y f) x f expects to have as a first argument some continuation for the recursive subproblems. Using the y f as a continuation, we see ...
I'm reading the r6rs Scheme report and am confused by the explanation of continuations (I find it to be too dense and lacking of examples for a beginner). What is this code doing and how does it ...
