NAME
   Clone::PP - Recursively copy Perl datatypes

SYNOPSIS
     use Clone::PP qw(clone);

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

     $d = clone($a);
     $e = clone($b);
     $f = clone($c);

     # or

     use Clone::PP;
     push @Foo::ISA, 'Clone';

     $a = new Foo;
     $b = $a->clone();

DESCRIPTION
   This module provides a clone() method which makes recursive copies of
   nested hash, array, scalar and reference types, including tied variables
   and objects.

   The clone() function takes a scalar argument and an optional parameter
   that can be used to limit the depth of the copy. To duplicate lists,
   arrays or hashes, pass them in by reference. e.g.

     my $copy = clone (\@array);
     # or
     my %copy = %{ clone (\%hash) };

SEE ALSO
   For a faster implementation in XS, see the Clone manpage.

   For a slower, but more flexible solution use the dclone function from
   <Storable>.
