enum --- support for enumerations ========================================
    An enumeration is a set of symbolic names (members) bound to unique, constant
    values.  Within an enumeration, the members can be compared by identity, and
    the enumeration itself can be iterated over.

        from enum import Enum

        class Fruit(Enum):
            apple = 1
            banana = 2
            orange = 3

        list(Fruit)
        # [<Fruit.apple: 1>, <Fruit.banana: 2>, <Fruit.orange: 3>]

        len(Fruit)
        # 3

        Fruit.banana
        # <Fruit.banana: 2>

        Fruit['banana']
        # <Fruit.banana: 2>

        Fruit(2)
        # <Fruit.banana: 2>

        Fruit.banana is Fruit['banana'] is Fruit(2)
        # True

        Fruit.banana.name
        # 'banana'

        Fruit.banana.value
        # 2
