From d047205c23b2729ba528d5c969f77671a10dfb83 Mon Sep 17 00:00:00 2001 From: Dag Brattli Date: Fri, 13 Feb 2026 19:37:44 +0100 Subject: [PATCH 1/4] [Python] Add HashSet and NestedPattern tests, fix HashSet operations for native sets The Python HashSet replacements were using JS method names (has, delete) that don't exist on Python's native set type. Fixed Count, Contains, Remove, UnionWith, IntersectWith, and ExceptWith to use Python-compatible helpers that work with both native set and custom MutableSet.
