 New Comment:

doesn't fix the bug, but a workaround:

function array_val($array, $key) {
	return $array[$key];
}

then you can do things like:

var_dump(array_val(array('a', 'b'), 1));

Supported dereferencing array indeces on arbitrary expressions.

Currently you can only dereference array indeces on variables
directly:

$a = array('a', 'b');
var_dump($a[1]);

but this does not work

var_dump(array('a', 'b')[1]);

neither does this:

function returnArray() {
    return array('a', 'b');
}
var_dump(returnArray()[1]);

or this:

$value = ($ns == 'foo' ? $thisArray : $thatArray)[0];
