Python 3

Pickles are kind of meant to be transient. They're not meant to be long term storage, because there's not a lot of guarantees around their parsability. And so this is something I worked on for about three months or something was just migrating all of our caches to to use Jason into the pickles. But then fall back and try to get the binary pickle, but then immediately replace it with the JSON version so that it just grows over time. We've never tried it. I think everyone's a little bit too scared, but it's definitely like not something we wanted to do.
