I wrote the below code

    def func_wrapper(func):
        from .decorators import wraps
        cfunc = __cacheit(maxsize)(func)
        @wraps(func)
        def wrapper(*args, **kw_args):
            r1 = func(*args, **kw_args)
            r2 = cfunc(*args, **kw_args)
            (hash(r1), hash(r2))
            if (r1 != r2):
                raise RuntimeError('Returned    values    are    not    the    same')
            return r1
        return wrapper
    return func_wrapper
