Consider jQuery to be the canary in the coal mine. Messing with `Object.prototype`, or most other prototypes you don't control, has been proven time and again to be bad practice. The old code didn't check to see if it was clobbering someone else's (admittedly ill-advised) `.each()` or `.merge()` extension to `Object.prototype` for example, so it didn't play well with others.
