Why would we want to even consider a new approach to handling keyword arguments which applies only to three dunder methods, `__getitem__`, `__setitem__` and `__delitem__`, instead of handling keyword arguments in the same way that every other method handles them? That's not a rhetorical question. If there is an advantage to making this a special case, instead of just following the same rules as all other methods, I'm open to hearing why it should be treated as a special case. > So for indexing > > b = arr[1, 2, a=3, b=4] > > Instead of > > __getitem__(self, (1, 2), a=3, b=4) > > Just do > > __getitem__(self, (1, 2), {'a': 3, 'b': 4}) That would be the effect of defining your method with signature: def __getitem__(self, index, **kwargs) so if you specifically want all your keyword arguments bundled into a dict, you can easily get it. -- Steven _______________________________________________ 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/RJGNYW6LH4VPSO2HULRLYKXBN5WSZTBT/ Code of Conduct: http://python.org/psf/codeofconduct/
