Well, I have no code that would benefit from this change. What's the point?
Sure, I use _parts_ of hash codes at times, but, e.g.,
index = the_hash_code & SOME_LOW_BIT_MASK
in Python couldn't care less about the sign of `the_hash_code` - it returns a
non-negative int regardless. The same applies if, e.g., SOME_LOW_BIT_MASK is
`(1 << sys.hash_info.hash_bits) - 1`, giving a full-width non-negative hash
without losing a bit of "entropy". But I've never felt a need for the latter.
Likewise for doing, e.g.,
index = the_hash_code % SOME_POSITIVE_PRIME
in Python. % takes the sign (positive here) of the modulus in Python.
So this _looks_ like pointlessly disruptive code churn to me. What killer use
case am I missing?
