Yes, I don't believe the PEP is suggesting any changes to list.__getitem__. If
you want to suggest such enhancements, I would suggest first sending a message
to the python-ideas mailing list or on discuss.python.org.

Ok, I see.
>>> a[1, 2, *[3, 4]]
Would still faith with PEP 646 because lists don't accept tuples, right?
>>> a[(1, 2, *[3, 4])]

Peter Tillema added the comment:
Right, I should have clarified it a bit more. I'm using NumPy arrays because
they allow indexing like this, where the input arguments are converted to a
tuple. So
a[1, 2, *[3, 4]]
is different than
a[[1, 2, *[3, 4]]]
This indeed only works on NumPy arra

Jacob wrote:
a[[0, *[0, 0], 0]]
which passes the *list* [0, 0, 0, 0] into __getitem__. In numpy, passing lists
into __getitem__ does things like array([1, 10, 100])[[2, 1]] --> array([100,
10]).
But I think Peter is requesting that the following work:
