The clone() function takes a scalar argument to copy. To duplicate lists, arrays or hashes, pass them in by reference. e.g. my $copy = clone(\@array); my @copy = @{ clone(\@array) }; my $copy = clone(\%hash); my %copy = %{ clone(\%hash) }; =head2 Multiple Implementations Depending on which modules are available, this may load Clone, Clone::PP, Util, Storable, or Class::MakeMethods::Utility::Ref. If none of those modules are available, it will C. =head1 SEE ALSO For the various implementations, see L, L, L, L, and L. See L for the underlying module loader and exporter functionality. =head1 CREDITS AND COPYRIGHT Developed by Matthew Simon Cavalletto at Evolution Softworks.
