Awesome, looks good. Can you settle the prettier job and then I'll approve?

Perf for this library sometimes doesn't work the way you'd expect in my experience. 

Ok I found a discrepancy in the benchmark code that I fixed in `main` and we can properly test this now

Ran it again and the perf is pretty much the same between latest and this branch

I think this is potentially a breaking change, probably can't land it safely in the current major version

@fbarbare could you update against `main` when you get a moment? This branch looks awesome!

Would love to see the benchmarks run for this vs current `main` as well

> @quantizor sounds good to me! Do you think it should live in `/src/types.ts` or `/src/sheet/types.ts`? src/types is good :)
