I found out that (<>) (in Data.Monoid) is missing, also. It would be nice to reexamine Prelude to export things we want to export.

Fwiw, (<>) was actually left-out as it wasn't required (it's just a an alias for `mappend`), *and* to keep our options open (or at least not make it more difficult) in terms of possible migration-plans available for the case we'd be moving 'Semigroup' to base/Prelude at some point in the future.
