MicroPython v1.18 on 2022-04-14; ESP32 module with ESP32
Type "help()" for more information.

Than was tried another way to mpy-cross CPython libs enum.py and type.py:

>>> import enum
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "./py/enum.py", line 3, in <module>
  File "./py/types.py", line 14, in <module>

@IhorNehrutsa ,
The (optional) MicroPython modules such as your proposal for Enum are managed in a separate repository : micropython-lib
So apart from the documentation , the implementation of the Enum class will need to be in a PR to micropython-lib
