Aside from the fact that your "never" somewhat dismisses the first however many years of web development (up to IE9) when `Function.prototype.bind` couldn't universally be expected to be supported, surely having a nice piece of syntax which is both shorter than writing out `function` and serves the purpose of binding the function in the way that, a good majority of the time, you actually want it bound, is a good thing?

As someone who's spent a lot of time writing CoffeeScript, I think ES6's fat arrows are a great thing, though I have my usual concerns about their confusing the hell out of people who may well have been writing JavaScript for a long time but in environments where they don't necessarily get exposed to new and exciting stuff. But hey, that's progress, I guess.
