The solution that I use is to write a function that returns a hash reference that is tied. Like this:
use Tie::IxHash
sub ordered_hash_ref {
tie my %hash, 'Tie::IxHash', @_;
return \%hash;
}
# time passes...
tie my %data, 'Tie::IxHash',
1 => ordered_hash_ref(
6 => ordered_hash_ref(
width => 53,
len => 16,
width_arr => [ 53 ],
mems => 1,
rows => 1
mux => 4,
len_arr => [ 16 ],
cols => 1,
),
),
;
This is nice if you like having your nested data structures declared compactly, albeit at the cost of having to put the function calls in there.

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).
