Reviving None-aware operators for Python

The idea of adding None-aware operators to Python has sprung up once
again. These would make traversing structures with None values in them
easier, by short-circuiting lookups when a None is encountered. Almost
exactly a year ago, LWN covered the previous attempt to bring
the operators to Python, but there have been periodic discussions stretching back to
2015 and possibly before. This time Noah Kim has taken up the cause. After some debate, he
eventually settled on redrafting the existing PEP to have a more limited scope,
which might finally see it move past the cycle of debate, resurrection, and abandonment that
it has been stuck in for most of the last decade.
