So hashes aren't ordered because the following doesn't work?
$h{foo} = 'a';
$h{bar} = 'b';
$h{baz} = 'c';
is(join(' ', values(%h)), "a b c");
I guess arrays aren't ordered either, then.
$a[2] = 'a';
$a[0] = 'b';
$a[1] = 'c';
is("@a", "a b c");
Order has to be imposed externally on the data in the case of arrays too. It's just there's a convenient way of doing that when the keyspace isn't sparse (namely, the range operator).

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).
