[Python-ideas] Additional LRU cache introspection facilities

Is anyone else interested in additional introspection facilities for the functools.lru_cache? You can view the cache hit and miss statistics using the cache_info() method, but you can't see what values actually are in the cache. That would be useful to me. I propose a method: @functools.lru_cache() def function(arg): ... function.cache_export() that returns a dictionary {arg: value} representing the cache. It wouldn't be the cache itself, just a shallow copy of the cache data. Any interest? -- Steve
