Comment (by sjakobi):

 Replying to [comment:17 Azel]:
 > I guess that's a fair point about `Monad` & co. And about the Arrow
 classes, they are but only by reference to external papers. I guess that
 just means we need to make sure the links to the papers stay live.

 Are we looking at the same docs? The haddocks for `Arrow`, `ArrowPlus`,
 `ArrowChoice` all have their laws spelled out right there.
