One of the propositions is to expose these implementations in a way that:

   1. The implementation used for functools.lru_cache can be
   chosen/switched.
   2. The current implementation in lru_cache can be used for other
   purposes.

Grako parsers, for example don't use lru_cache in memoization because they
need finer control about what gets cached.
