+
 Substantial superficial but breaking changes due to the adoption of timely `0.27`.
 Primarily that the `Stream` contained by `Collection` is not `Clone` by default, and is now conventionally passed owned rather than by reference.
 The necessary fix-ups are to convert to owned collections, and where needed to clone the collection, which requires that its container implement `Clone`.
