I don't think this makes scope in JS much more complicated. If you were teaching JavaScript to someone, you'd either not mention let (if old browsers still matter), or not mention "var". You wouldn't ever need to tell a newbie about both. "const" is extra, but is it really so complex?
>One of the strengths of object literals is that you can use them as dictionaries. obj.foo === obj['foo'].
That's not a strength when it means you can't use anything other than strings as keys. It destroys your ability to 'treat functions, types, literals, etc in interesting ways' if those interesting ways involve using them as dictionary keys.
>For me, I almost never use == so it should be gotten rid of.

Backwards compatibility.
