3.14 Sequences and Streams

Sequences and streams abstract over iteration of elements in a collection. Sequences allow iteration with for macros or with sequence operations such as sequence-map. Streams are functional sequences that can be used either in a generic way or a stream-specific way. Generators are closely related stateful objects that can be converted to a sequence and vice-versa.
