 `_EventKey._key` uses `id()` of listener function. This causes problem
 when method is used since in python new method object (with different id,
 but equal when compared with `==`) is created each time it's accessed. As
 a result `event.remove` fails for it with exception "`InvalidRequestError:
 No listeners found for event …`".
