Do you mean only when there's defaults defined? As in this returns `0`:
(function(a = 1, b = 2, c = 3){
return arguments.length;
})(undefined, undefined, undefined);
For compatibility with a lot of existing JS code, the following must
return `3`:
(function(a, b, c){
return arguments.length;
})(undefined, undefined, undefined);
