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.
