I’m glad you figured it out because I was going to have to resort to copying the code in F# interactive to figure out what was going on!

As you point out ‘g’ takes in 2 arguments, one of which is a continuation so in the 2nd one I guess we’d attempt to add 1 to a partially applied function if it actually compiled.

Ah, I get it. I made a mistake. Function g is also a continuation function so the second option doesn’t even compile.

I’m reading Real-World Functional Programming at the moment and after reading the bit about continuations I thought I needed to know more about it and I came across your post.

I had to think some time about the function:

let f n k = g (n + 1) (fun x -> k(x + 1))

Is it correct that this is exactly the same as:

let f n k = k (g(n + 1) + 1)

If so, then why would you write it one way or the other? Thanks.

[...] my colleague Alex Scordellis' recent post about lambda passing style I spent some time trying out a continuation passing style style on some of the code in one of our controllers to see how different the code would look [...]
