I don't follow. Is this really the intended behavior? It seems quite
unintuitive that the original array would be modified by *empty* loops.
Suppose I create an include file that loops through $_GET variables
with references:
foreach ($_GET as &$get) { /* empty loop */ }
Subsequent foreach() loops on $_GET would cause corruption. Seems
dangerous.
When would this behavior be desired?
!intuitive && !desired == bug ?

Richard, enumerator exhausted, repeat your sub-sequence again you
will get it
e.g pointer and pointed
<?php
$items = array('apple', 'banana', 'carrot');
print_r($items);
foreach ($items as &$item) { }
print_r($items);
foreach ($items as $item) { }
print_r($items);
