Interesting little side note, for anyone who doesn't already know: at the C level, Python objects have two ways of implementing addition and multiplication. The first is through the "numeric" `tp_as_number` interface, which exposes our well-known `__add__` / `__mul__` trios of methods. The second is through the `tp_as_sequence` interface, where we can define "concat" / "inplace concat" / "repeat" / "inplace repeat" functions to do the same thing (at least it's mostly the same when working in the Python layer). Sequence repetition and concatenation are very strongly baked into the Python's object model, even if it's not immediately obvious from further up. The C implementation for this proposal uses the latter interface, for a few technical reasons that I won't dive into here. This means, though, that it really can be accurately thought of as "dict concatenation". _______________________________________________ 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/WLYGCUL6JJFIIHC36MWCP2VNYXKV5CP4/ Code of Conduct: http://python.org/psf/codeofconduct/
