I am CPython contributor :)\r\nAnd I've recently noticed that for the last 22 years we have some special casing for `org.python.core.PyStringMap`.\r\n\r\nHere are they:\r\n- https://github.com/python/cpython/blame/db115682bd639a2642c617f0b7d5b30cd7d7f472/Lib/copy.py#L59-L62\r\n- https://github.com/python/cpython/blame/db115682bd639a2642c617f0b7d5b30cd7d7f472/Lib/pickle.py#L101-L105\r\n- https://github.com/python/cpython/blame/db115682bd639a2642c617f0b7d5b30cd7d7f472/Lib/xml/sax/__init__.py#L98-L100\r\n\r\nThe question is: do we still need it?\r\n\r\nSome concerns:\r\n1. It imports code from some third-party module in the stdlib. This is the only place (there might be some other cases that I am not familiar with, please proove me wrong) where we do it. It might be a source of some unexpected results if user has the same package structure. It might be even related to security, because importing third-party modules is never safe in Python\r\n2. Jython seems to only support 2.7 a the moment, so we might not need this anymore in our core library 🤔 \r\n\r\nPlease, share your vision on this 🙂 ","author":{"url":"https://github.com/sobolevn","@type":"Person","name":"sobolevn"},"datePublished":"2022-11-14T09:02:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/217/jython/issues/217"}
