(1c) Section "Guard against changing dict during iteration" says "Sadly, the dictionary version proposed in this PEP doesn't help to detect dictionary mutation." Why not? Wouldn't that mutation involve replacing a value, which ought to trigger a version change?
Yes it would, but mutating a dictionary value during iteration is legal, so we cannot use the __version__ [1] change to tell us that something illegal happened.
[1] We're not going to call it __version__ are we? Seems like __cache_token__ is a much better name.
