1. all streams are EventEmitter instances, and this is mentioned on the
docs first. so everything works for stremas as well including 'error'. just
attach a listener on 'error' and you're safe.
2. both ways work. you could subclass or just create a Writabel instance
and attach a new _write function. It's more a matter of style and applied
paradigm. some prefer the mixin-approach, some inheritance. me personally
prefer the mixin approach, because it's cleaner and more focused on actual
work, than pseudoclass-boilerplating.
