I'd be in favor. We'd need another name, since the current closure
predicate is already standardized to `by:`.
(Or, as I propose above, once `Ordering` comes to the stdlib, we can just
have it as `func sort<U: Comparable>(_ ordering: Ordering, by: (T) -> U)`,
called like `sort(.ascending) { $0.age }`.)
