-1 on breaking the existing Monoid instance. I'd prefer either: a) A newtype for the additional Monoid instance, or b) providing an associative operator equivalent to the new Monoid instance I'm not convinced that the replacement instance is more useful, let alone useful enough to break everything depending on containers. A lot of packages both on and off Hackage depend on Edward's code, almost all of which would break as a result of this change.
