I should also make it clear that the collision hash((1,0,0)) == hash((1,-2,-2)) that I reported is due to the algorithm, it's not due to some bad luck that 2 numbers happen to be the same. There are also many more similar hash collisions for tuples (all involving negative numbers) due to the same underlying mathematical reason.

I still don't understand why you don't consider it a problem. It may be a tiny problem, not really affecting the correct functioning of CPython. But, if we can fix this tiny problem, why shouldn't we?
