does it really work? how do you deal with concurrent access?

@0r1g Yeah, it works. In short, Angular "compiles" the JavaScript and HTML into its own "runtime-thing", where all services are singletons (i.e. one object for each service), and there's a model-view-update loop that fires events as things happen: https://docs.angularjs.org/guide/databinding. It is neat.

Would this work when you have controllerAs syntax and don't have implicit inheritance?
