Reading through this thread, I was thinking of a comtime signed integer (basically a `UInt` whose sign is given by a parameter). I think this could solve some of the issues mentioned here. Nonetheless, I would be surprised if other people had not been thinking about this already, so I would appreciate comments as to why this is not a good option.

To keep the current thread focused, I would propose to discuss this here, where I also provide some more details and a reference implementation: [Pre-Proposal: a comptime signed int for indexing](https://forum.modular.com/t/pre-proposal-a-comptime-signed-int-for-indexing/2462)
