The way you have quoted this suggests it is being said by the author, whom you are disagreeing with. It's not: it's being said by someone else (in an issue filed against the repo), and the author also mostly disagrees.
Sorry, yes this is not from the mouth of the author, however he seemed to agree with the premise that async/await is unergonomical and that performance is its only reason to exist, which I am trying to dispute (at least in the context of how Rust does it, which is much better than the JS version for instance)
Indeed. I read it as something written by the author. Double-checking revealed it was written by spacejam that did post the same argumentation over and over here on HN.
