my first suspicion would be the signature of `set.add`. will investigate

Code sample in [basedpyright playground](https://basedpyright.com/?pyrightVersion=1.28.0&typeCheckingMode=standard&code=DYAgvCDaCMA0ICYC6AoAzgLhGgpgF0gHsAjAKxwGM8lwQBvaAXxQBMsWBLKosyveEuSo0IDLAmboAdAEMWLABTAAlCBABiEADlCIAO4yATgDsOxgObS5ilqo3bdBk2cutIwESGhrNxx0dMLFCA) ```python l = [1, 2] s: set[object] = {1} d: dict[object, object] = {1: 2} s.add(l) # No warning s.add(d) # No warning d[l] =...
