For cloning purposes, may I suggest using either the Storable modules
dclone method
use Storable qw(dclone);
my $copy = dclone($some_ref);
or perhaps the Clone module
use Clone qw(clone);
my $copy = clone($some_ref);
Back to your problem at hand, the reason you get 1 as a result of
the thaw method, is because it is documented to return an
array. And an array in scalar context returns the number of elements,
which in your case is 1. Try something like this:
@copy = thaw freeze $hashref
Autark.

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).
