[issue35300] Bug with memoization and mutable objects

New submission from bolorsociedad : The decorator functools.lru_cache seems to not work properly when the function to be memoized returns a mutable object. For instance: >>> import functools >>> @functools.lru_cache() ... def f(x): ...return [x, x + 1] ... >>> a = f(4) >>> print(a) [4, 5
