At the very least, I've seen Data::Dumper get painfully slow with complex data structures. It might be easier and faster to simply roll your own. Something like this would probably get you 90% of the way there: foreach my $key1 (keys %hash) {
print "$key1:\n";
foreach my $key2 (keys %{$hash{$key1}}) {
print " $key2:\n";
foreach my $key3 (keys %{$hash{$key1}{$key2}}) {
print " $key3:\n " ,
join (",",@{$hash{$key1}{$key2}{$key3}}),
"\n";
}
}
}
$perlmonks{seattlejohn} = 'John Clyman';
