=head1 SYNOPSIS

    use Clone 'clone';

    my $data = {
       set =&gt; [ 1 .. 50 ],
       foo =&gt; {
           answer =&gt; 42,
           object =&gt; SomeObject-&gt;new,
       },
    };

    my $cloned_data = clone($data);

    $cloned_data-&gt;{foo}{answer} = 1;
    print $cloned_data-&gt;{foo}{answer};  # '1'
    print $data-&gt;{foo}{answer};         # '42'

You can also add it to your class:

    package Foo;
    use parent 'Clone';
    sub new { bless {}, shift }

    package main;

    my $obj = Foo-&gt;new;
    my $copy = $obj-&gt;clone;

=head1 DESCRIPTION

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

C&lt;clone()&gt; takes a scalar argument and duplicates it. To duplicate lists,
arrays or hashes, pass them in by reference, e.g.

    my $copy = clone (\@array);

    # or

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

=head1 SEE ALSO

L&lt;Storable&gt;'s C&lt;dclone()&gt; is a flexible solution for cloning variables,
albeit slower for average-sized data structures. Simple
and naive benchmarks show that Clone is faster for data structures
with 3 or fewer levels, while C&lt;dclone()&gt; can be faster for structures
4 or more levels deep.
