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 lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
