[issue41220] add optional make_key argument to lru_cache

[Raymond Hettinger]

What is the given example trying to accomplish?  It looks like every possible input list would be cached using just the first element of the list.  Would cached_func([10, 20, 30]) and cached_func([10, 11, 12]) return the same sum?  If not, why would that be desireable?
