bpo-38659: [Enum] add _simple_enum decorator (GH-25497)
add: * `_simple_enum` decorator to transform a normal class into an enum * `_test_simple_enum` function to compare * `_old_convert_` to enable checking `_convert_` generated enums `_simple_enum` takes a normal class and converts it into an enum: @simple_enum(Enum) class Color: RED = 1 GREEN = 2 BLUE = 3 `_old_convert_` works much like` _convert_` does, using the original logic: # in a test file import socket, enum CheckedAddressFamily = enum._old_convert_( enum.IntEnum, 'AddressFamily', 'socket', lambda C: C.isupper() and C.startswith('AF_'), source=_socket, ) `_test_simple_enum` takes a traditional enum and a simple enum and compares the two: # in the REPL or the same module as Color class CheckedColor(Enum): RED = 1 GREEN = 2 BLUE = 3 _test_simple_enum(CheckedColor, Color) _test_simple_enum(CheckedAddressFamily, socket.AddressFamily) Any important differences will raise a TypeError
