interface Stream<out A, out E = never, out R = never>A Stream<A, E, R> describes a program that can emit many A values, fail

Streams are pull-based with backpressure and emit chunks to amortize effect
evaluation. They support monadic composition and error handling similar to
Effect, adapted for multiple values.
