I'm afraid I still don't quite understand the relationship between \@arr in the constructor and the [] array ref in TIEARRAY. Would you mind rewriting this example in a way that demonstrates the "two-faced" aspect of what I'm trying to achieve? There is something like it in perltie, but it doesn't actually have an additional 'new' constructor to abstract away the tie'ing (and uses a hash) and I couldn't quite rework it in the way I intend.
Thanks so much!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
