…fication, r=Nadrieril Pattern Migration 2024: try to suggest eliding redundant binding modifiers This is based on rust-lang#136475. Only the last commit is new. This is a simpler, more restrictive alternative to rust-lang#136496, meant to partially address rust-lang#136047. If a pattern can be migrated to Rust 2024 solely by removing redundant binding modifiers, this will make that suggestion; otherwise, it uses the old suggestion of making the pattern fully explicit.

This is a tracking issue for reserving space in match ergonomics in Rust 2024 for RFC 3627 and other proposals for the future of match ergonomics.
Rules
move(whether or not behind a reference), writingmut,ref, orref muton a binding is an error.move.About tracking issues
Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions. A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature. Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.
