I actually really need this for my project. Can I send a PR?

[hsluoyz]

sure, please send a PR :)

Btw, I think you can implement it as a wrapper of the enforcer, like this one: https://github.com/casbin/casbin/blob/master/enforcer_synced.go

Sounds good. I was thinking of also implementing the same adapter pattern used for persistence, so that the cache can be either in-memory (default) or redis. It'll also give the user an opportunity to provide their own cache implementation in case they don't want to use the default in-memory cache.
