Thank you! This is a great PR — I didn't believe there was a fix as straightforward as this one.

As it happened I was also working on a PR for this separately (#3533). It doesn't have the forehead-smacking elegance of this one, but it allows us to remove about 90 LOC from the compiler, and will handle weird edge cases involving destructuring assignments. So I'm going to close this in favour of that one — but thanks anyway 🍻
