not:
 class Color(enum.Enum):
 red = "red"
 blue = "blue"
 green = "green"
or:
 class Color(enum.Enum):
 red = object()
 blue = object()
 green = object()
or:
 class Color(enum.Enum):
 red
 blue
 green
This last one is to the point but raises a NameError.
Personally, I have not found enum.Enum all that appealing. If I have
needed such enums in my code, I have usually just defined:
 class MyClass:
 RED = "RED"
 BLUE = "BLUE"
 GREEN = "GREEN"
