I feel that it's a bit more than syntax sugar - I'll use this to normalize APIs between different third-party libraries (including the Scala standard library) so that I don't have to remember e.g. whether Slick implemented recover() for DBIOs (hint - it didn't, which breaks the mental abstraction of "this is like a Future, but different") or whether Map()s have a `filterValues()` method to match their `filterKeys()` (again, no).
