Description:
------------
---
From manual page: http://www.php.net/language.generators.syntax
---
The Yield command which has the syntax:

yield $var;

In it's basic form doesn't work and issues on CLI the following error:

Parse error: parse error in test.php on line 7

Test script:
---------------
Test script is the example posted on the generators page:

<?php
function gen_one_to_three() {
    for ($i = 1; $i <= 3; $i++) {
        // Note that $i is preserved between yields.
        yield $i;
    }
}

$generator = gen_one_to_three();
foreach ($generator as $value) {
    echo "$value\n";
}

Expected result:
----------------
The yield command should work as documented.
