+/// ## What it does
+/// Checks for membership tests on `list` and `tuple` literals.
+///
+/// ## Why is this bad?
+/// When testing for membership in a static sequence, prefer a `set` literal
+/// over a `list` or `tuple`, as Python optimizes `set` membership tests.
+///
+/// ## Example
+/// ```python
+/// 1 in [1, 2, 3]
+/// ```
+///
+/// Use instead:
+/// ```python
+/// 1 in {1, 2, 3}
