Support calls to enum classes #7027
Description
When an enum class is created, the EnumType metaclass replaces its original constructor with a new implementation that performs a value-based lookup. The following should therefore type check without errors.
from enum import Enum
class Example(Enum):
A = (1, 2)
def __init__(self, value, other) -> None:
self._value_ = value
self.other = other
Example(1) # This should not generate an error
