New Comment:
That means there's no way to use an Iterator and advance the array
pointer more than once per iteration. You can't use a for loop, and you
can't use while + list/each, so you're only option is to use foreach and
use the Iterator specific methods such as:
$iter->next();
etc. which precludes you from writing code that can handle arrays OR
Iterators effectively (unless you actually check the type of the
array/Iterator and handle it differently) such as:
if(!($my_arr instanceof Iterator))
{
while(current($my_arr))
{
list($key,$value) = each($my_arr);
//do stuff... do we need to advance the pointer again?
//yes we do ...
list($key,$value) = each($my_arr);
//do stuff... do we need to advance the pointer again?
//not this time ...
}
}
else
{
while($my_arr->valid())
{
... etc ...
}
}
which is highly cumbersome. An Iterator should just behave like an
array when it comes to Iteration, what's the point of having it not work
with list/each?

This was recently discussed on the developers list and decided to keep
the current behavior which is iterating over the object's property table

Sorry, my desired result should have been:
0: one
1: two
2: three
0: one
1: two
2: three

Description:
------------
I can use an Iterator with foreach(), however if I attempt to iterate
over it using list/each it does not behave as expected. Basically I'd
just like to be able to treat an Iterator as I would an array.
Reproduce code:
---------------
sample code at:
http://www.workingsoftware.com.au/iterator_test.phpt
Expected result:
----------------
this is not so much expected, as desired result:
0: one
1: two
2: three
Actual result:
--------------
0: one
1: two
2: three
MyIteratorarr: Array
