Range support is something that came up, and I think it’s a great idea as well. My question now is do we support both `CountableRange` and `CountableClosedRange`?

It would be nice to leverage range support instead of a start and end value IMHO.

Hello swift evolution, I would like to propose a unified approach to `random()` in Swift. I have a simple implementation here https://gist.github.com/Azoy/5d294148c8b97d20b96ee64f434bb4f5. This implementation is a simple wrapper over existing random functions so existing code bases will not be affected. Also, this approach introduces a new random feature for Linux users that give them access to upper bounds, as well as a lower bound for both Glibc and Darwin users. This change would be implemented within Foundation.

I believe this simple change could have a very positive impact on new developers learning Swift and experienced developers being able to write single random declarations.

I’d like to hear about your ideas on this proposal, or any implementation changes if need be.
