Clone - recursively copy Perl datatypes
=======================================[![Build Status](https://travis-ci.org/garu/Clone.png?branch=master)](https://travis-ci.org/garu/Clone)
[![Coverage Status](https://coveralls.io/repos/garu/Clone/badge.png?branch=master)](https://coveralls.io/r/garu/Clone?branch=master)
[![CPAN version](https://badge.fury.io/pl/Clone.svg)](https://metacpan.org/pod/Clone)This module provides a `clone()` method which makes recursive
copies of nested hash, array, scalar and reference types,
including tied variables and objects.```perl
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:
```perl
package Foo;
use parent 'Clone';
sub new { bless {}, shift }package main;
my $obj = Foo->new;
my $copy = $obj->clone;
````clone()` takes a scalar argument and duplicates it. To duplicate lists,
arrays or hashes, pass them in by reference, e.g.```perl
my $copy = clone (\@array);# or
my %copy = %{ clone (\%hash) };

--------[Storable](https://metacpan.org/pod/Storable)'s `dclone()` 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 `dclone()` can be faster for structures
4 or more levels deep.COPYRIGHT
