[New-bugs-announce] [issue23030] lru_cache manual get/put

[Constantin]

New submission from Constantin:

In an effort for improved communication between stacked decorators, I would like to propose that all decorators providing caching mechanisms should provide the functions cache_info, cache_clear, cache_get and cache_put. The standard lib only provides functools.lru_cache as caching decorators, which already implements the former two. I have attached a patch to provide the latter two.

On python-ideas there was also the idea to create a cache data structure and then have a decorator take its data structure as an argument. But it was argued that this could lead to some optimizations of the caching being impossible.

I think my suggested approach should not impose a problem on highly optimized caching code, because every cache - no matter how optimized - must have some functionality to add something to the cache and lookup something in the cache.
