[New-bugs-announce] [issue40504] Restore weakref support for lru_cache wrappers

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

The pure python version of lru_cache() wrappers supported weak references.  It's not essential, but I have used it a couple of times.  In the spirit of PEP 399, the C version should add back the weakref support (and a test).
