I've never used the feature and don't intent to.

A related annoyance is the trailing comma at the end of stuff (probably a
leftover from a previous edit). For example:

def fun(a, b, c,):


Parses fine. But the one that has bitten me is the comma at the end of a
line:

>>> x = 1,
>>> x

(1,)

>>> x == 1, # inconsistency?

(False,)

>>> x == (1,)

True

>>> y = a_very_long_call(param1, param2, param3), # this trailing comma is
difficult to spot

I'd prefer that the syntax for creating one-tuples requires the
parenthesis, and that trailing commas are disallowed.

Cheers,
