Useless trailing comma
Reports the trailing commas in parameters lists and closures' use lists that do not bring any benefit.
In a single-line list, a trailing comma is redundant and can be removed.
In a multiline list, if no line break is provided after a trailing comma, it becomes impossible to easily add, remove, or move lines.
