What about actually putting it visibly into the stdlib? Except for files, I didn't see much about caching there, which seems like a missing battery to me. Why not do it as with the collections module and add stuff as it comes in?
Caching is a rather large topic to focus on in a single stdlib module or package. It means radically different things to different people. The pattern we're talking about there is probably more something like memoization, so 'memo' or 'memoization' could b a reasonable module name. Maybe it could provide a decorator that you configure with things like how many entries max, the expiration policy (or different policies could have different decorators), and how to compute the memo key from the arguments to the function (the default could be the repr() of the argument tuple). -- --Guido van Rossum (python.org/~guido)
