Wraps functools.lru_cache, so it's not referenced at import in Python 2 and unsupported Python 3 distributions. Args: maxsize (int|None): From Python functools docs: "...saves up to the maxsize most recent calls... If maxsize is set to None, the LRU feature is disabled and the cache can grow without bound."
