Not really the same, since that issue was more about fast division. But it's the same spirit. It looks like I was more enthusiastic back then; now I'm older and grumpier. It's great to have this stuff, but I don't think it belongs in core Python: I'd much rather that the core Python integer implementation remain simple, portable and low-maintenance, and work well for the domain it's intended for: small-to-medium size integers. Cryptographic-size integers with a few hundred to a few thousand digits should be fine; number-theoretic work requiring hundreds of thousands of digits should use gmpy2 or something similar.
