Allow the four required arguments to be passed by position or keyword, matching CPython and fixing pytest Node.warn calls. Add regression coverage for mixed calls, warning instances, and invalid argument binding. Codex implemented the fix and regression tests, ran validation, and drafted this commit and the PR description. The contributor manually verified the warning reproducer. Assisted-by: Codex:GPT-6
