You mean this MultiValueEnum implementation? (If not I don't understand the
question, could you elaborate?)
No, this is the opposite of aliases, because an alias is when the same value
have multiple names, but this is when the values are used to lookup the same
name.
I use it when very similar values have the same meaning like:
class Suit(MultiValueEnum):
CLUBS = '♣', 'c', 'C', 'clubs', 'club'
DIAMONDS = '♦', 'd', 'D', 'diamonds', 'diamond'
HEARTS = '♥', 'h', 'H', 'hearts', 'heart'
SPADES = '♠', 's', 'S', 'spades', 'spade'
Also it can be used for ECP testing (Equivalence class testing) like this:
from http.client import responses
class ResponseEnum(MultiValueEnum):
GOOD = [status for status in responses if 200 <= status <= 299]
BAD = [status for status in responses if not (200 <= status <= 299)]
I did not think about this use case, but I think it's very interesting and
useful.
