If you want equal but distinct, you can give them distinct values and
define an __eq__ method that compares them as equal. Because of this
though I do take some issue with the Planet example in the docs:

https://docs.python.org/3/library/enum.html#planet

If any planets happened to have the same mass and radius (which I
realize would be unlikely in this case), the example would fail. Using
the value of the enum for both identity and data conflates the two
concepts and leads to pitfalls.
