NAME

SYNOPSIS

    use Clone 'clone';

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

    my $cloned_data = clone($data);

    $cloned_data->{foo}{answer} = 1;
    print $cloned_data->{foo}{answer};  # '1'
    print $data->{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->new;
    my $copy = $obj->clone;

DESCRIPTION

"clone()" 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) };
