This was moved to bugbear, but we forgot to delete the file.

-/// ## What it does
-/// Checks for set literals that contain duplicate values.
-///
-/// ## Why is this bad?
-/// In Python, sets are unordered collections of unique elements. Including a
-/// duplicate value in a set literal is redundant, and may be indicative of a
-/// mistake.
-///
-/// ## Example
-/// ```python
-/// {1, 2, 3, 1}
-/// ```
-///
-/// Use instead:
-/// ```python
-/// {1, 2, 3}
-/// ```
