Quite a few years since I used `with` the last time. Not going back to that one. `call/apply/bind` are normal functions though, not some fancy syntax construct

Quite a few years since I used `with` the last time. Not going back to that one. `call/apply/bind` are normal functions though, not some fancy syntax construct, and `this` is important if you want to play with prototypes/Object.create, which is what you want to do if you found class syntax sugar lacking in features/extensibility/overrideability.
