[$] Not coalescing around None-aware

The wish for a "None-aware" operator (or operators) islongstanding within the Python community. While there is fairlywidespread interest in more easily handling situations where a value needs to betested for being None before being further processed, there ismuch less agreement on how to "spell" such an operator (or construct) andon whether the language truly needs it. But the idea never seems to goaway, with long discussions erupting every year or two-and no resolutionreally in sight.
