Description:
------------
See Bug #23022.

Since we can have arrays that contain arrays, arrays that contain functions, functions that return arrays and functions return functions;

and since both arrays and functions effectively define mappings between their arguments/indices and their values;

and since we can already dereference array accesses into higher dimensions (i.e., we can write $foo[1][2]);

I would like to be able to do the same thing with the other three cases. The bug cited above asks for $foo(1)[2]; I'd like to add a request for $foo[1](2) and $foo(1)(2).

Please, sir: can we have these?

Reproduce code:
---------------
<?php
$func = function($a) {
    return function($b)use($a) {
        return $a+$b;
    };
};

echo $func(5)(3);
?>

Expected result:
----------------
8

Actual result:
--------------
Parse error: syntax error, unexpected '(', expecting ',' or ';' in C:\test.php on line 9

Perhaps I should just add....
although I reference Bug #23022, I'm not asking for this to be over _arbitrary_ expressions, only arrays and callables. I don't want this language turning into Perl :)
