NAME
       Clone - recursively copy Perl datatypes

SYNOPSIS
         use Clone;

         push @Foo::ISA, 'Clone';

         $a = new Foo;
         $b = $a->clone();

         # or

         use Clone qw(clone);

         $a = { 'foo' => 'bar', 'move' => 'zig' };
         $b = [ 'alpha', 'beta', 'gamma', 'vlissides' ];
         $c = new Foo();

         $d = clone($a);
         $e = clone($b);
         $f = clone($c);

DESCRIPTION
       This module provides a clone() method which makes recursive copies of nested hash, array,
       scalar and reference types, including tied variables and objects.

       clone() takes a scalar argument and an optional parameter that can be used to limit the
       depth of the copy. To duplicate lists, arrays or hashes, pass them in by reference. e.g.

           my $copy = clone (\@array);

           # or

           my %copy = %{ clone (\%hash) };

       For a slower, but more flexible solution see Storable's dclone().
