There is some precedent for 'sortOn' as the naming convention should we choose to go ahead with it.

Having some mechanism by which we can explicitly request the Schwartzian transform like that as opposed to 'element by element' By functions strikes me personally as a good idea and sufficiently non-trivial to pass the "Fairbairn threshold" in my book.

+1 from me.

+1 here, seems like a nice design

+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) -- Live well, ~wren
