[New-bugs-announce] [issue17528] Implement dumps/loads for lru_cache

[Francesco Frassinelli]

New submission from Francesco Frassinelli:

Hi,
I propose to change the public API of functools.lru_cache in order to make the cache persistent when the program is restarted.
It could be implemented using two different functions (dumps/loads), where the cached is exported into a classical dictionary and restored in the same way.
A third argument could be also added to provide the initial cache (calling the loads function internally after the initialization).

I think this could be an important enhancement because lru_cache will probably implemented in C and try to export cache contents it will be not possible (see: http://bugs.python.org/issue14373).
