Research direction

Start by reading the attached tes_attr1.py examples, then test6.py, to understand the reported getattr and reraising behavior. Trace the relevant CPython interpreter entry point for attribute lookup and determine the expected exception flow. Done means the triggering AttributeError is available to getattr and the attached reraising examples behave as intended, with regression coverage.
