#![allow(non_snake_case)]

// Ensures that we don't spend an unnecessary amount of compiler time building
// suggestions for mistyped methods. This used to happen because when we had method
// lookup failures, we would do subsequent method lookups, and those would themselves
// do extra work that was unnecessary for the purposes of suggestions.
// Fixed by #125100.
