The easiest way to go is to wait to start caching until you know the cache size
you want:
def foo(a, b, c):
pass
size = get_user_request()
foo = lru_cache(foo, maxsize=size)
If there is a subsequent need to change the cache size, just rewrap it:
size = get_user_request()
original_function = foo.__wrapped__
foo = lru_cache(foo, maxsize=size)
