Well, I'm not a (complete) beginner, but I wouldn't know how to do that.

While I understand the idea of monads (I've digested Philip Wadler's http://citeseerx.ist.psu.edu/viewdoc/summary?doi=, I haven't managed to make the jump to seeing how that would be obviously useful in Racket.

Can anyone illustrate how that solution would work in Ben's example here?
