Línea de trabajo

Start by reproducing the behavior from the attached new_patch_fails.py file on the affected Python versions, comparing Python 2.7 with Python 3.5 as described. Then trace the interpreter-core handling of assigning and deleting a class's new attribute. Done means the reported class can be instantiated after that sequence without the TypeError, with regression coverage for the behavior.
