Auto generating multi-method default handler with type casting for variadic argument list #522

Closed arakov closed 2 months ago

The following code should work:

B;

C
{
    B cast()
        = new B();
}

singleton E
{
    load(params B[] o)
    {
        for(int i := 0, i < o.Length, i += 1)
        {
            console.writeLine(o[i])
        }
    }
}

public program()
{
    var b := new B();
    var c := new C();

    var e := E.load(b,c);
}

The output should be

$private'B
$private'B
