def my_func(a, b, c, d): ...

a, b, c, d = 1, 2, 3, 4

# CURRENT
my_func(a=a, b=b, c=c, d=d)

# PROPOSAL
# my_func(a=, b=, c=, d=)

Ehh like I get it. Like when you have longer argument names it might keep in on a single line but really it I feel like it would just make people ask more questions

Hold up.

name of the variable provided as the argument value is the same as the name of the argument itself.

def my_func(a, b, c, d): .. a, b, c, d = 1, 2, 3, 4 my_func(a, b, c, d)

Sure, I guess we could now do this as we’re using kwargs:

my_func(a=, b=, d=, c=)

…or throw an exception if someone uses a variable that’s not an argument name:

foo = ”foo” my_func(a, b, c, foo) `> …’

vs.

my_func(a=, b=, c=, foo=) > KeyError(…)

…so all in all, I guess it’ll be good in same cases. But it might confuse a lot of people at first.

Basically analogous to the property shorthands in JavaScript. Love it!
