please leave the declare_lint invocations as they were. It's become the de-facto style and often it can't be changed anyway due to the length of the message.

I changed it back, but note that you can see in this PR that there are places I didn't change that use this style. I also think having declare_lint!( and declare_lint_pass! neatly together on two lines like this is quite readable.

hmm. maybe I'm just so conditioned to clippy's use of declare_lint. Having the three components be in three different lines allows me to immediately see the entire lint instead of having to parse a line.

Implement another internal lints cc rust-lang#49509 This adds ~~two~~ one internal lint~~s~~: 1. LINT_PASS_IMPL_WITHOUT_MACRO: Make sure, that the `{declare,impl}_lint_pass` macro is used to implement lint passes. cc rust-lang#59669 2. ~~USAGE_OF_TYCTXT_AND_SPAN_ARGS: item 2 on the list in rust-lang#49509~~ ~~With 2. I wasn't sure, if this lint should be applied everywhere. That means a careful review of 0955835 would be great. Also 73fb9b4 allows this lint on some functions. Should I also apply this lint there?~~ TODO (not directly relevant for review): - [ ] rust-lang#59316 (comment) (not sure yet, if this works or how to query for `rustc_private`, since it's not in [`Features`](https://doc.rust-lang.org/nightly/nightly-rustc/syntax/feature_gate/struct.Features.html) 🤔 cc @eddyb) - [x] rust-lang#61735 (comment) - [x] Check explicitly for the `{declare,impl}_lint_pass!` macros r? @oli-obk
