In all the cases I've observed, it did not make the code clearer. Using
bools as integer is frowned upon in some languages, in others it's
simply not possible.
You can find comments on the original pull request #8131 that agree with
this point of view.

Address issues 9739 and 9782
This PR fixes#9739 in the manner I suggested in https://github.com/rust-lang/rust-clippy/issues/9739#issuecomment-1296802376.
This PR also fixes the compilation failures in #9782 (but doesn't address `@e00E's` other objections).
Fixes#9739

changelog: Fix two `needless_borrow` false positives, one involving borrows in `if`-`else`s, the other involving qualified function calls
Add `manual_is_ascii_check` lint
Addresses https://github.com/rust-lang/rust-clippy/issues/9290
This PR adds new lint `manual_is_ascii_check`, which detects comparison with ascii ranges using `matches!` macros.
As I mentioned as following in the Issue;
> Yes, that's true. we'll start small and then grow it.
> So I'll try to handle matches! macro with single range as suggested above.
However during writing first version, I was thinking that the changes to support alphabetic and digits will be small patch, so I made a single PR in hope review cost can be reduced.
changelog: add new lint [`manual_is_ascii_check`]

Extend `needless_collect`
Extends when `is_empty` and `contains` are linted.
`is_empty` will be linted when `<IterTy as Iterator>::Item` is the same as `<CollectTy as IntoIterator>::Item`. This can be a false positive if the `FromIterator` implementation filters out items, but I don't know of any which do that also implement `IntoIterator` with a matching `Item` type.
`contains` will be linted when the argument type is `&<IterTy as Iterator>::Item`. It has the same false positives as `is_empty` with the same note that I know of nothing that actually causes that in practice.
changelog: Lint `needless_collect` when `is_empty` or `contains` is called on some non-std types
Move needless_collect to nursery
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: [`needless_collect`]: Move `needless_collect` to nursery (Now allow-by-default)
After chatting with a few folks, it seems like `needless_collect` is giving false positives pretty regularly (https://github.com/rust-lang/rust-clippy/issues?q=is%3Aissue+is%3Aopen+needless_collect). We're big supporters of clippy in Nushell, and it's one of the passes we require for CI, but we've had to disable this particular lint. Perhaps it should be moved to the nursery until it's improved?
(apologies if this isn't the right approach to disabling a lint by default. I tried to follow the idea I saw other PRs doing in the past)
Add allow-print-in-tests config
Add a config, allow-print-in-tests, that can be set in clippy.toml which allows the usage of `[e]print[ln]!` macros in tests.
Closes#9795
---
changelog: Enhancement: [print_stdout], [print_stderr]: Can now be enabled in test with the `allow-print-in-tests` config value
improve `filesearch::get_or_default_sysroot`
`fn get_or_default_sysroot` is now improved and used in `miri` and `clippy`, and tests are still passing as they should. So we no longer need to implement custom workarounds/hacks to find sysroot in tools like miri/clippy.

Update CONTRIBUTING.md with changelog guidance
`@xFrednet` I cribbed some text of yours from https://github.com/rust-lang/rust-clippy/pull/9743#issuecomment-1295892442 and did some light editing in the hope that others might find it.
