mypy reports an error when passing enum values as arguments

Bug Report

Starting with https://github.com/python/mypy/commit/1a04c073260c13107abfab6ae0ff4c8cc214eb54 @sterliakov enum values assigned to functions are typed as Callables. This seems to make mypy report an error when passing enum values to functions that expect the enum.

To Reproduce

from enum import Enum
import operator

class Op(Enum):
    ADD = operator.add
    SUB = operator.sub
    MUL = operator.mul

def takes_op(op: Op, x: int, y: int):
    return op.value(x, y)

print(takes_op(Op.ADD, 2, 2))

Expected Behavior

No error

Actual Behavior

/Users/psawicki/test.py:12: error: Argument 1 to "takes_op" has incompatible type "Callable[[Any, Any], Any]"; expected "Op"  [arg-type]

Your Environment

• Mypy version used: mypy 1.20.0+dev.1a04c073260c13107abfab6ae0ff4c8cc214eb54 and up
• Mypy command-line flags: mypy ~/test.py
• Mypy configuration options from mypy.ini (and other config files): None
• Python version used: 3.13.5

Esegui l'esempio Python minimo dell'issue con mypy 1.20.0+dev.1a04c073260c13107abfab6ae0ff4c8cc214eb54 e traccia come vengono tipizzati i membri dell'enum a cui sono assegnati valori chiamabili. Aggiungi un test di regressione per passare Op.ADD a takes_op e conferma che mypy non segnali alcun errore di tipo dell'argomento.
