Research direction
The issue concerns mypy's handling of import * inside Python class bodies; no specific files or tests are named. Start by reproducing the case and locating the code and tests that validate import statements in class scope. Done means mypy rejects this construct in Python 3 while preserving the stated Python 2 distinction.
