NAME
       Clone - recursively copy Perl datatypes

SYNOPSIS
	 package Foo;
	 use parent 'Clone';

	 package main;
	 my $original = Foo->new;
	 $copy = $original->clone;

	 # or

	 use Clone qw(clone);

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

	 $d = clone($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 duplicates it. To duplicate lists, arrays or hashes, pass them in by reference. e.g.

	   my $copy = clone (@array);

	   # or

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

SEE ALSO
       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 less levels, while dclone() can be faster for structures 4 or more
       levels deep.
