> I think it would be interesting to see to what extent the Rust 2024 changes alleviated the problem since it only changed if let, but I haven't found that information (yet).

The second link from Reddit, https://redlib.catsarch.com/r/rust/comments/1v54et2/what_are... , claims that some issues were made worse in practice in his experience by Rust edition 2024.

Regarding "super let", it looks interesting, but I am not sure about the details of it. This is the tracking GitHub issue https://github.com/rust-lang/rust/issues/139076 . There is also the challenge of backwards compatibility, which makes the feature harder to make good, I suspect.
