I didn't expect these results of using Data::Dumper (with Useperl(1)) and
Clone::clone together. This snippet:
#!/usr/bin/perl -w
use strict;
use Clone;
use Data::Dumper;
printf "Clone: %s Data::Dumper %s\n",
$Clone::VERSION,
$Data::Dumper::VERSION;
my $orig = {
# This could be arbitrariliy complicated/nested
# - this suffices for a demo
# of the probem
'array' => [ 1,2,3 ]
};
# Put it throught Data::Dumper with Userperl(1);
my $d = Data::Dumper->new([$orig]);
$d->Useperl(1);
$d->Dump();
# Make a clone - it should be identical, I guess
my $clone = Clone::clone($orig);
# See that the clone has a different structure in array
# (length of $$clone{array} is 0)
printf "orig: %d clone %d\n",
scalar(@{$$orig{array}}),
scalar(@{$$clone{array}});
Produces this output:
Clone: 0.29 Data::Dumper 2.121_14
orig: 3 clone 0
I would have expected
Clone: 0.29 Data::Dumper 2.121_14
orig: 3 clone 3
Since the orig and the clone should have been identical. Right?
Is there a bug here? Where?

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).
