For example, `f(a=1, b=2)` and `f(b=2, a=1)` + differ in their keyword argument order and may have two separate cache + entries. + If *maxsize* is set to ``None``, the LRU feature is disabled and the cache can grow without bound. The LRU feature performs best when *maxsize* is a power-of-two. -- 2.47.3
