What about adding this change also in the GetWithExpiration https://github.com/patrickmn/go-cache/pull/75/files#diff-56ffa6659747ba7a23d2b5597a4cda5dR143 ?

I think you'll only want to call Delete if the cache has an eviction function.

This will strongly affect on Get operation performance, because mutex will be locked for RW-access (another concurrent read operations will be also locked). Nevertheless, janitor will also lock cache while deleting other expired items. |
