Port, board and/or hardware

Pico W (RP2040)

MicroPython version

MicroPython v1.22.2 on 2024-02-22; Raspberry Pi Pico W with RP2040

Reproduction

>>> from collections import namedtuple
>>> namedtuple('a', ['a'], defaults=[1])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: function doesn't take keyword arguments

Expected behaviour

Expected the creation of a NamedTuple with defaults.

Observed behaviour

Exception as shown in repro code.

Additional Information

The keyword-only argument of defaults was added in Python 3.7 according to the Python docs. I could not find any mention of this change or disparity in the MicroPython docs.

I did, however, find that the change to other arguments becoming keyword-only in Python 3.6 is not listed as implemented in the MicroPython docs.

It seems like the lack of keyword argument support might be intentional - I'm not sure if this means it should be considered a feature request and/or docs improvement instead?
