Whereas I'm hoping that you might come around to the idea of three, :-) Your version is simpler in the sense that it uses fewer new dunders. However, it comes at the cost of more complexity, both conceptually and implementation-wise, and requires constructing new objects on every indexing operation, which is a fairly expensive thing to do. My version is based on a vision of what the indexing dunders might have been like if we'd had positional and keyword indexing from the beginning. If Python 4000 ever happens, the old dunders could be cleanly removed, just leaving the new ones. There's no such upgrade path for your version. -- Greg _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/DYBHWO4ZKU6YDD4VMCNVP75DT3GN6TNM/ Code of Conduct: http://python.org/psf/codeofconduct/
