Agreed - the poster though was asking for trailing commas to be
permitted in argument lists

  do_somthing(1,2,3,)

would be a call with three parameters. I was suggesting that if this
was allowed, it could only work if the parameter list was
parenthesized, as there would otherwise be the ambiguity shown above.
