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
r? `@Jarcho`
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`]

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
Changelog for Rust 1.65
Roses are red,
violets are blue,
another 6 weeks,
another changelog, yahoo!
This did not rhyme,
luckily, not a crime.
I want to say something smart,
but I am out of time.

Improve `needless_lifetimes`
This PR makes the following improvements to `needless_lifetimes`.
* It fixes the following false negative, where `foo` is flagged but `bar` is not:
```rust
fn foo<'a>(x: &'a u8, y: &'_ u8) {}
fn bar<'a>(x: &'a u8, y: &'_ u8, z: &'_ u8) {}
```
* It flags more cases, generally. Previously, `needless_borrow` required *all* lifetimes to be used only once. With the changes, individual lifetimes are flagged for being used only once, even if not all lifetimes are.
* Finally, it tries to produce more clear error messages.
changelog: fix `needless_lifetimes` false negative involving functions with multiple unnamed lifetimes
changelog: in `needless_lifetimes`, flag individual lifetimes used only once, rather than require all lifetimes to be used only once
changelog: in `needless_lifetimes`, emit "replace with `'_`" warnings only when applicable, and point to a generic argument
Add lint for confusing use of `^` instead of `.pow`
fixes#4205
Adds a lint named [`confusing_xor_and_pow`], it warns the user when `a ^ b` is used as the `.pow()` function, it doesn't warn for Hex, Binary... etc.
---
changelog: New lint: [`confusing_xor_and_pow`]
Warn when `clippy::restriction` is enabled via the command line
Currently it catches `#![warn(clippy::restriction)]`, it'll now catch `-W clippy::restriction` from the CLI. Also tweaks the message slightly
changelog: [`blanket_clippy_restriction_lints`]: Warn when `clippy::restriction` is enabled via the command line
fix `undocumented-unsafe-blocks` false positive
This fixes#9142 by iterating over the parent nodes as long as within a block, expression, statement, local, const or static.
