Perhaps I don't understand the intended usage model, but since a DualContext[F] contains a ContextShift[F] would it make sense to provide an implicit DualContext[F] -> ContextShift[F]. I have had to write this signature def stream[F[_]: Sync](implicit cs: ContextShift[F], dual: DualContext[F]) which seems redundant. Alternatively, the cs inside DualContext could be made implicit for importing.
