I've posted an article to the Patterns list archive at the ACM, re the
combination of iterators and factory methods.  From the introduction:

"This article describes what an active iterator is, and how to use a
factory method to create one.

There are also examples of using System.Address_To_Access_Conversions to
get around the limitation of not having in out parameter modes for
functions."


The patterns archive is at the following URL:

<http://www.acm.org/archives/patterns.html>

The iterator article is under the November 1998 link, and is titled
Iterator and Factory Methods Combined.

The article is based on a presentation I gave to the Patterns WG at the
recent SIGAda conference in Washington, DC, USA.
