Confusable idents detection uses a type `BTreeMap<Symbol, Span>`. This is highly dubious given that `Symbol` doesn't guarantee a meaningful order. (In practice, it currently gives an order that mostly matches source code order.) As a result, changes in `Symbol` representation make the `lint-confusable-idents.rs` test fail, because this error message: > identifier pair considered confusable between `ｓ` and `s` is changed to this: > identifier pair considered confusable between `s` and `ｓ` and the corresponding span pointers get swapped erroneously, leading to an incorrect "previous identifier" label. This commit sorts the relevant symbols by span before doing the checking, which ensures that the ident that appears first in the code will be mentioned first in the message. The commit also extends the test slightly to be more thorough. |
