Exactly my point. Arrow functions and destructuring assignments are great, but we've put up with function() { ... } for the last 20 years, so I'm pretty certain we can wait a couple of more years and not get bogged down in these crazy tooling chains to achieve so little.

and if we insist on crazy tooling chains, how about getting some real benefit – like coffeescript (?-operator anyone) or typescript (yes, typing can help, just look at swift)?
