[issue46925] Replace key if not identical to old key in dict

2022-03-05 Thread Jarek Potiuk

How about if we make PR instead to the documentation about this behaviour? 

I think this behaviour is a little surprising (you need to know the internals 
of how WeakKeyDict keys are constructed and checked) and while I understand you 
do not want breaking change, maybe this should be explained to the users and 
example given how to apply the workaround?

Just following the "least surprise" principle.
