Description: On the Apple M1 Max, this change makes no difference. I get 303/304 nsec per loop before and after the edit. Would anyone care to run this on their builds and report back the results? % ./python.exe -m timeit -r21 -s 'n=100' -s 'from random import expovariate as r' -s 'v1=[r(1000) + r(0.125) for i in range(n)]' 'sum(v1)' 1000000 loops, best of 21: 304 nsec per loop Issue: gh-100425
