@rbuckton would the below be possible with extractors? const x & { a } = something; β€” or β€” arr.map((fullObj & { propA }) => (…)) …or would this sort of destructuring rely on pattern matching, cc @drosenwasser @ljharb @mpcsh_ @rkirsling @tabatkins

I... don't like this. How is this better than const {x, y} = C(subject) And now there is a tuple randomly happening?
