flufl.enum disallows this:

class Color(Enum):

  red = 1

  blue = 2

  green = 1 # oops!

Has it been decided that this is now allowed? If this is indeed the case, then Color(1) is a problem. The options are:

A. Return either Color.red or Color.green

B. Throwing an error

Do we have a decision on this? Personally I think the latter is better; the former is error prone and doesn't seem to be useful too often.

class Color(Enum):
  red = 1
  blue = 2
Color.green = Color.red
