    Description

      https://www.python.org/dev/peps/pep-0584 added a new syntax for dict union in Python 3.9
      I am seeing 3 new opcodes in CPython that look relevant:

      SET_UPDATE
      DICT_MERGE
      DICT_UPDATE

      We should add tests for type inference involving these operations and see if we need additional changes to https://github.com/apache/beam/blob/master/sdks/python/apache_beam/typehints/opcodes.py
