Brent Westbrook 24b1b1d52c [syntax-errors] Duplicate attributes in match class pattern (#17186) ... Summary -- Detects duplicate attributes in a `match` class pattern: ```python match x: case Class(x=1, x=2): ... ``` which are more analogous to the similar check for mapping patterns than to the multiple assignments rule. I also realized that both this and the mapping check would only work on top-level patterns, despite the possibility that they can be nested inside other patterns: ```python match x: case [{"x": 1, "x": 2}]: ... # false negative in the old version ``` and moved these checks into the recursive pattern visitor instead. I also tidied up some of the names like the `multiple_case_assignment` function and the `MultipleCaseAssignmentVisitor`, which are now doing more than checking for multiple assignments. Test Plan -- New inline tests for both classes and mappings.		2025-04-03 17:55:37 -04:00
