Dictionaries are one of the most frequently used data structures in python. It contains data in the form of key value pairs. While processing the data with dictionaries, we may need to iterate over the items in the dictionary to change the values or read the values present in the dictionary...
and the issue isn't happening inmy CI environmentsthat also rely on importlib_metadata 3.8 and pluggy. Moreover, when looking at#290, I don't see anything in particular where a dictionary size might be altered. There isthis line, but theinfosandeggsare mutated in the__init__so shouldn'...
