Hi, I propose the inclusion of the node/io EventEmitter class[1] in core targeting ES7.
Reasoning: The .on/.emit model is very popular[2] in the ECMAScript land, and it suits the language a lot. We use events pretty much everywhere in the JS land. It makes sense for the standard EventEmitter class used commonly to be included in core. With ES6 classes, userland code classes extending[3] the EventEmitter class would be pretty common and useful even in environments like browsers. Notes: I think the `.once` method from the node/io EventEmitter class _could_ be left out from standard implementation mainly because we would rather use Promises there. Although it would also make sense to keep it in for further compatibility.
