So you need to dereference the arrays. @$arrayref.

If you just need to know what's in the hash, use Data::Dumper. It does a great job of expanding references and can be made to do all sorts of pretty printing.

use Data::Dumper;
print Data::Dumper->Dump([\%yourhash], ["name of your hash"]), "\n";

You can also use that to print your arrays and such.
