Code with argument unpacking not working

Code:
```php
function foo(int ...$a) {
	return $a;
}

$ints = [1,2];
foo(...$ints);
```

Result:
`Compile Error: Cannot use positional argument after argument unpacking`

Generated code causing the error:
```php
return foo(\PHPSandbox\wrapByRef(...$ints, \PHPSandbox\PHPSandbox::getSandbox('__PHPSandbox_ff7c8ab064063e1d4d509dfbadda498e')));
```
