1) Ah, the ValuePipe is (relatively) new; thanks for the pointer. 2) You have to explicitly `.group` in Scoobi as well; it transforms a DList[(K,V)] to a DList[(K, Iterable[V])] or similar. You don't have to call `.toTypedPype` to get map and friends, though, since it's just a DList. 3) I've actually written this exact integration, so I'm glad it's the approved method! The global, mutable Mode made me nervous, IIRC.

The global Mode is gone in 0.9.0. And there is an implicit from Grouped to TypedPipe, so you don't need to call .toTypedPipe (that directly seems less likely to cause problems, especially given we have mapValues and filter on Grouped, so we should avoid needlessly leaving the Grouped representation).

Neat! It looks like things are changing fast; I'll have to do another read-through.
