Is this a breaking change? It feels borderline. Keyword-only subscripts are permitted. The positional index will be the > empty tuple: > obj[spam=1, eggs=2] > # calls type(obj).__getitem__(obj, (), spam=1, eggs=2)
I.e. consider: >>> d = dict() >>> d[()] = "foo" >>> d {(): 'foo'} I don't really object to this fact, and one could argue it's not a breaking change since a built-in dict will simply raise an exception with keyword arguments. However, it does make the empty tuple the "default key" for new objects that will accept keyword indices. -- The dead increasingly dominate and strangle both the living and the not-yet born. Vampiric capital and undead corporate persons abuse the lives and control the thoughts of homo faber. Ideas, once born, become abortifacients against new conceptions.
