Channel

trait Channel [-T] extends Channel[T]

Abstraction for unification of sender and senderFuture for later reply. Can be stored away and used at a later point in time.

The possible reply channel which can be passed into ! and tryTell is always untyped, as there is no way to utilize its real static type without requiring runtime-costly manifests.
