Or

     class Color(Enum):
         values(BLACK,
            RED, GREEN, BLUE,
            CYAN, YELLOW, MAGENTA)

where values() ignores its arguments and ends the
definition phase.

This would also provide a way to avoid relying on
language guarantees of evaluation order. The initial
lookup of the names could assign arbitrary values to
them, and then values() could remap them to sequential
values based on the order it receives them in.
