Looks extensive and I'll likely try using the module at some point. One thing, why not stash all the function methods under a "ring" or "cache" attribute, eg @ring.lru() def foo() .. foo.cache.update() foo.cache.delete() .. This might be less likely to clash with any existing function attributes (if you're wrapping a 3rd party function say).
