Using the example from the docs:

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

Actual output (py 3.11):

>>> Color(0, 1)
TypeError: <enum 0> cannot extend <enum 'Color'>

Expected output- not 100% sure but, something along the lines of:

• TypeError saying "... takes 1 positional argument but 2 were given" like Color() does, or
• ValueError saying "... is not a valid Color" like Color(0) does

The current metaclass error message is a bit confusing.
