I don't feel strongly about allowing ()-lookup in addition to []-lookup, but

flufl.enum disallows this:

class Color(Enum):
   red = 1
   blue = 2
   green = 1 # oops!

Has it been decided that this is now allowed?

I don't recall if it was decided. I think it should be possible to
create aliases like this. The main thing I care about is that
Color.green == Color.red.

I believe that Barry had decided that it should be prohibited. I objected, and Nick pointed out that although declaring two enums with the same value inside the class is prohibited, aliases are supported by adding them from the outside:

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

Color.green = Color.red

which satisfies me.

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

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