Description:
------------
Any construct of the form myFunc()[x] or $object->myFunc()[x] results in a fatal error, even if myFunc() returns an array. Putting the expression in parentheses (like (myFunc())[x]) doesn't help. The only remedy seems to be using an intermediate variable.

Reproduce code:
---------------
<?php
function getArray() { return array(1, 2, 3); }

echo getArray()[1];
?>

Expected result:
----------------
"2" being output

Actual result:
--------------
Parse error: syntax error, unexpected '[', expecting ',' or ';' in test.php on line 4
