#45906 [NEW]: Cannot use square brackets on a function

From:             david dot c dot cook+php at gmail dot com
Operating system: 
PHP version:      5.2.6
PHP Bug Type:     Feature/Change Request
Bug description:  Cannot use square brackets on a function

Description:
------------
Cannot use square brackets to directly reference array elements in the
returned value of a function. As a flexible language that can do pretty
much anything, it seems logical to be able to achieve this on one line,
without having to first assign the return value to a temporary variable.

Reproduce code:
---------------
function test()
{ 
   return array('a', 'b'); 
}

//desired
echo test()[0];

//workaround
//$temp = test();
//echo $temp[0];

Expected result:
----------------
a

Actual result:
--------------
Parse error: syntax error, unexpected '['
