;.write operations on a stream:
:A.1) May do partial writes and return the data that has not yet been read.
:A.2) May do partial writes and return the length of data that has been written.
* Wes Garland
:B) Block until all the data has been written to the underlying layer (partial writes may be handled with a different method or options; unspecified atm).
* Daniel Friesen
* Kris Kowal
* Tom Robinson

=== Notes ===
* Kris Kowal thinks that B).write should return `this` to allow chaining.
