It does better. It supports callbacks, including callback objects with multiple methods. So to define a stream, you just send the other side an object with a `write()` and an `end()` method. The other side calls `write()` for each chunk of the stream, then eventually calls `end()`. You can also give the stream a `[Symbol.dispose]()` method which will be called when the other side disconnects, so you can detect premature disconnect.
