Hi Dennis
I know a weird question that you likely already thought about but still why
are you not using a combination of array and hash?
$hash->{value1} = [ value2, value3, value4, ... ]
It would save you a lot of headaches in looping over all values that are on
that one line because how are you going to easily handle a situation where
you have a hash of hashes with an undefined depth without having to jump to
a lot of difficult hoops to make it work properly?
