Each time a dictionary is created, the global version is incremented and the dictionary version is initialized to the global version.
A detail, but why not set the version tag of new empty dictionaries to zero, always? Same after a clear(). This would satisfy the condition: equality of the version tag is supposed to mean "the dictionary content is precisely the same".
You're right that incrementing the global version is useless for these specific cases, and using the version 0 should work. It only matters that the version (version? version tag?) is different. I will play with that. If I don't see any issue, I will update the PEP. It's more an implementation detail, but it may help to mention it in the PEP. Victor
