# This module is used to map the old Python 2 names to the new names used in
# Python 3 for the pickle module. This needed to make pickle streams
# generated with Python 2 loadable by Python 3.
# This is a copy of lib2to3.fixes.fix_imports.MAPPING. We cannot import
# lib2to3 and use the mapping defined there, because lib2to3 uses pickle.
# Thus, this could cause the module to be imported recursively.
