(From the Perl FAQ)

How do I print out or copy a recursive data structure?

The Data::Dumper module on CPAN is nice for printing out data structures, and FreezeThaw for copying them. For example:

Code
    use FreezeThaw qw(freeze thaw); 
$new = thaw freeze $old;

Where $old can be (a reference to) any kind of data structure you'd like. It will be deeply copied.
