Suggestion to Rename Effect.iterate and Effect.loop for Clarity
Hi, just a suggestion: maybe it would be clearer if Effect.iterate were renamed Effect.whileDo, Effect.loop were renamed Effect.whileDoAccum. Then we could also add Effect.doWhile and Effect.doWhileAccum (same as the other ones but the first step is called before the predicate). I could make a PR if you think this suggestion brings anything.
