+1 for adding the decorate-sort-undecorate function to the API.

-1 for adding RULES, since this transformation is not always an optimization.

+1 for the name sortOn. Luke Palmer discusses the *On naming scheme,
and I've seen/used it elsewhere.

-0 for the name sortWith. I think "with" is too generic a preposition;
it works best as a two-place predicate imo (e.g., fooWithKey)
