I am not sure you and the OP are talking about the same thing. Bundling a caching layer without even trying to write caching algorithms -- particularly if such a layer is serving multiple purposes -- sounds to me like what the parent is calling a "general-purpose caching framework", probably overly abstracted too as these things are wont to be. I would be super cautious incorporating this kind of black-box stuff. Even if the docs have 10 LOC examples, there can be all kinds of unexpected quirks that you would need to be aware of before doing anything. I read the OP as talking about specific, single-purpose caching techniques -- e.g. when you need to repeatedly compute a function of arbitrary parameters, it can help a lot to simply store values for the more common parameter combinations.
