No, you missed the point. this need to be valid "Harmony code" in order to
avoid a migration tax:
function f() {
return g.apply(undefined,arguments);
}
no ... or any othe

All langua
point 1 is utopia since ...varname breaks syntax in any case
second point would be easier like this ?
function (arg1obj={a,b,c}, p=[x,y]) {
}

1) arguments is needed for backwards compatability (no migration tax)
2) it is useful with destructing parameters:
function ({a,b,c}, [x,y]) {
if (arguments.length < 2) ...
...
var arg1obj = argruments[0];

I am not sure I am missing something but I think arguments could disappear
without problems, being easily simulated like this:
function f1(...arguments) {
f2.apply(this, arguments);
f2(...arguments);
let [a,b,c,...rest] = arguments;
// etc etc
}
Am I wrong ?

Hi,
Here is the behavior I would like:
function f( a, b, ...rest ) { }
f( 1, 1 );// ok
f( 1, 1, 1 );// ok
f( 1, undefined );// ok
f( 1 );// Error: missing parameter
Because since you can't reference a and b as properties of an objec
6 matches
