Here I link up up some very useful material by Robert Norris (@tpolecat) and Martin Odersky (@odersky) to introduce Monad laws and reinforce the importance of checking the laws. E.g. while Option satisfies the laws, Try is not a lawful Monad: it trades the left identity law for the bullet-proof principle.
