Are there other cases where we suggest adding a feature if using nightly? If so, that might be better!

Yeah, that could be done, though I think we plan on stabilizing precise capturing soon, so not totally certain about the value. Also, having things gated on "is this a nightly compiler" adds one more weird case that's impossible to test 😅

Actually I think I'll just open a follow-up that at least leaves a @bors r=oli-obk rollup |

…better-sugg-apit, r=oli-obk Fix precise capturing suggestion for hidden regions when we have APITs Suggests to turn APITs into type parameters so they can be named in precise capturing syntax for hidden type lifetime errors. We also note that it may change the API. This is currently done via a note *and* a suggestion, which feels a bit redundant, but I wasn't totally sure of a better alternative for the presentation. Code is kind of a mess but there's a lot of cases to consider. Happy to iterate on this if you think the approach is too messy. Based on rust-lang#127619, only the last commit is relevant. r? oli-obk Tracking: - rust-lang#123432
