Generic key type about ccache HOT 2 OPEN

Never came up. The value change is pretty straightforward.

I think the biggest issue with the key is the bucketing and getting a hash key out of any value. Off the top of my head, don't know how to do that without requiring a hash function (or the key type to implement a HashCode function).

Some advanced functionality wouldn't work, like DeletePrefix - but I think it would be fine to fail in those cases.

Great to hear (I mean, you seem very open to introducing this).

But true, there's probably no easy way of supporting the hashing logic, other than defining a new interface that all key types would need to implement.
