=head1 NAME

Clone - recursively copy Perl datatypes

=head1 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);

=head1 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) };

=head1 SEE ALSO

L<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.
