Typecast to an array :)

[negoziator]

When calling ->get(..) without parameters, PHP will default the empty array to null

One way of calling it without this, would be to call get([]) with an empty array.
That seems like a bad behavior.

Just a neat little trick is to let the user call the function with null and then just typecast the array.

@negoziator unfortunately, this repository contains generated code and can't be modified directly. I'm curious about this though:

PHP will default the empty array to null

When I run similar code, I don't see it casting anything to null:

function foo($arg = []) {
    $other = [];
    print_r(array_merge($other, $arg));
}

foo();

// Array
// (
// )

I think there might be an issue a bit deeper which we need to keep looking for.

If it happens that there is a generator problem, we can work on addressing it there, but I'm not entirely sure that's the case yet.

Let's continue the discussion and research in the original PR since I think it's likely a fix will originate there. :)
