Description

The project won't compile when a function with more than one optional argument is called from an array, with first argument empty, and providing the subsequent ones.

Steps To Reproduce

Start a blank project.

Create a new script.

Paste the below code into the script and Run (F5)

-------- CODE -----------

var thisfunctionptr = function(_num1 = 1, _num2 = 2){
return _num1 + _num2;
}
var _array = [];
_array[0] = thisfunctionptr;
var _result = 0;
_result = _array[0]( , 2);
show_debug_message("empty 1st optional argument test: " + string(_result));

This one was found in the help channels, and I can confirm it. If the first argument is set as undefined it does run properly.
_result = _array[0]( undefined, 2);
It's only when the first argument is left blank that it doesn't.
