Re: [Haskell-cafe] Coroutines

Andrew was recently asking about co-routines. A couple of years ago, I was in much the same position as him; although I am pretty sure I had heard the term before, it seemed like a mysterious idea with no practical use.

Besides the point that people have already made that lazy evaluation gives you similar control as coroutines, I wanted to point out how simple it is to implement coroutines. Here's a simple implementation that ddarius made on IRC a few months back off-the-cuff. I kept it around on codepad because its cool: http://codepad.org/GwtS6wMj
