This should probably also update the lint documentation:
rust-clippy/clippy_config/src/conf.rs

This lint should probably check that the closure doesn't have parameter- or return type annotations since that can help type inference or make the map closure act as a coercion site.
Not your problem though, that could be a PR on its own, unless you also want to try to fix that here ^^.
Examples where the machine applicable suggestion breaks: coercions, inference

I will have a try fixing this, but I think I will open a separate PR so this one doesn't get too cluttered ^^

Add documentation update hint using `cargo collect-metadata` This adds a little reminder to update the documentation in the book using `cargo collect-metadata` after changing the lint configuration since this can easily be missed (been there done that 🙈). > Yeah a note would be good, would be good for us to see if we can make it automatic also _Originally posted by `@Alexendoo` in #11757 (comment) Regarding the automation Im not sure whats the best option here. I thought about a kind of a "semi-automated" way, e.g. a `cargo dev` command which runs the "is the documentation updated" check (and maybe other useful checks) locally and reminds the user of updating the documentation so this gets caught before pushing. changelog: none
