Description:
------------
PHP parser doesn't allow for array index operation to be used on a
result of a function call. I propose a patch to allow such a
construction.
Reproduce code:
---------------
<?php
function car_brands() {
return array("chevy", "hummer");
}
print car_brands()[1] . "\n";
?>
Expected result:
----------------
"hummer"
Actual result:
--------------
Parse error: syntax error, unexpected '[' in test.php on line 5
