    Streams offer a better way than collections to incrementally read and write a sequence of elements. There are easy ways to convert back and forth between streams and collections.

    • Streams may be either readable, writeable or both readable and writeable.
    • To convert a collection to a stream, define a stream “on” a collection, e.g., ReadStream on: (1 to: 1000), or send the messages readStream, etc. to the collection.
    • To convert a stream to a collection, send the message contents.
    • To concatenate large collections, instead of using the comma operator, it is more efficient to create a stream, append the collections to the stream with nextPutAll:, and extract the result by sending contents.
    • File streams are by default character-based. Send binary to explicitly make them binary.
