in reply to Deep Copying of Nested Data-Structures

personally, i like the following, nicked shamelessly from the font of merlyn. nice esp. if you do not want the overhead of another module.

sub deepcopy{
    my $this = shift;
    if (not ref $this){
    $this;
    }
    elsif (ref $this eq "ARRAY") {
    [map deepcopy($_), @$this];
    }
    elsif (ref $this eq "HASH"){
    scalar  { map { $_ => deepcopy($this->{$_}) } keys %$this };
    }
    else { die "what type is $_?"}
}

hope that helps,
