title: Coroutines in Scheme (R5RS)
body: <p>So I first came across the concept of coroutines in lua and lua's implementation was more or less understandable.. I'm learning scheme now and I understand that the same functionality is implemented with call/cc, but I'm having a bit of trouble wrapping my head around how exactly one would go about achieving this. Anyone know an easy tutorial or something on the subject?</p>
