src/tools/clippy/clippy_lints/src/unnested_or_patterns.rs

 use rustc_ast::{self as ast, DUMMY_NODE_ID, Mutability, Pat, PatKind};
 use rustc_ast_pretty::pprust;
 use rustc_errors::Applicability;
 use rustc_lint::{EarlyContext, EarlyLintPass};
 use rustc_session::impl_lint_pass;
 use rustc_span::DUMMY_SP;
+use std::boxed::Box;


Why is this necessary?

to shadow use rustc_ast::PatKind::*; above which contains a variant named Box

Ok, maybe add a comment?

Did you grep for P< afterwards? I see some comments got changed, so hopefully yes. r=me once the tests are green.

@bors p=1 because conflict-prone

Yes I did, if I searched for it correctly, there's only one mention of it left and its the release notes of Rust 1.15.0.

What is this?

This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing ca77504 (parent) -> 41ede7b (this PR)

Test differences

Show 60 test diffs

60 doctest diffs were found. These are ignored, as they are noisy.

Test dashboard

Run

armhf-gnu: 4917.0s -> 5493.3s (11.7%)

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
