Edit Question
Title
Body
In arrow do notation, you can use the rec keyword to write recursive definitions. So for example: rec name <- function -< input input <- otherFunction -< name How can this ever evaluate? It seems like it would just go into an infinite loop or something. I know it evaluates to the loop arrow combinator, but I don't understand how that works either. EDIT: that powers example is really helpful. How would you write that with do notation, though? I assume you would need to use rec.
