+1700 lines is more than I have time to review in-depth at the moment. I'll trust your good judgement.

AI comments, right? I'd remove them and just let the code do the talking (in general, not just here; I already spot several in quickjs.c)

Rule of thumb: comment why, not what, and only when the why is not obvious when looking at the code itself.

Yep, and sure thing, I opened as draft do a few more passes on it.

Could you please share some good merged PR or a commit with similar stuff added to compare for better understanding ? ❤️

Not sure what you mean, can you rephrase?

This is the implementation itself, there is no other.

Ben made an inception PR but it didn't include the new syntax.

This PR implements the entire spec.

can you rephrase?

I mean not about this exact spec, but another apriori well implemented. for keywords for or const or something like that where one can see the entire pipeline from keyword register in ast (like here) to its implementation itself. if nothing comes in mind, nevermind - I just found the implementation almost got it already. new noob questions:

• what are gen/* sources ? (they misled me in the search of impl itself in the commit)
• why one large source quickjs.c ? to avoid using Make or what ? I've been using sqlite, and the onefile-approach has been used for ease of amalgamation, and they generate it afaik.
