Not all browsers have implemented the spec yet. But you should read the spec before proposing changes to it!

Subject: Re: let function

That's not what I see, in strict mode at least, which I assume most people consider de facto by now!

From V8:

    SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function.

Similar error from SpiderMonkey.

Subject: Re: let function

I guess 'cause that cannot be scoped, let's say in a for loop ... but yeah, I think that's not the most needed thing in the language right now, yet another shortcut with double reserved words one after the other

Why not use a function declaration instead?

Propose adding support for

    let function foo() {};

which would have the equivalence of:

    let foo = function foo() {};

The idea is to support the normal scoping of let, but without forcing you to repeat yourself when naming the function, whilst still having the function's name property be set.

This would trivially extend to const and var. Also, possibly class.

Thanks
