An option for comma-dangle so that it works on function calls too

When does this rule warn? Please describe and show example code: It should warn for this:

func(
    a,
    b
)

Adding a comma after b should solve it.

Is this rule preventing an error or is it stylistic? stylistic

Why is this rule a candidate for inclusion instead of creating a custom rule? well, it’s just a simple option for comma-dangle rule.

Are you willing to create the rule yourself?

no

For someone who googles and comes to this page: this is already done in eslint-plugin-babel, the rule name is babel/func-params-comma-dangle.
