Variable argument count?

Try:

PHP Code:

function Foo(bar, baz)
{
    echo({ bar, baz });
    echo(params);
}

Foo(1, 2, true, 999); 


Will echo:

1, 2
-- Comment: 'true' is represented as 1.
1, 2, 1, 999

0 in Graal is literally translated as 'null', and will print absolutely nothing to the RC. An empty string literal will obviously print nothing as well.

In C#, it's similar in this manner:

PHP Code:

// C#
private void Foo(params object[] parameters)
{
     var bar = parameters[0];
     var baz = parameters[1];
     
     Console.WriteLine("Result: " + bar + ", " + baz);
}

Foo(1, 2);

// OUTPUT:
// Result: 1, 2
