I agree. The fact that you have to write library code defensively to still work depending on how your method's call, or that you have to use an awkward bind to preserve the `this` context of a method is so annoying and error-prone to me.
Even when you remember to perform the awkward bind / Function.prototype.call / Function.prototype.apply / var self = this; you still may already be inside of another context where this is not correctly defined. So then your code LOOKS even more like it will work thanks to the cargo cult magic ceremonies you've performed perfectly, but in the wrong place. It's like going into the bathroom like you're supposed to, but then taking a shit on the floor right next to the toilet, then flushing.
