yes! This is exactly it!. Perfect.
Just another question for the icing on the cake. When using the ++ on the
$hash{$key}++ how do I get the number of times every list was seen? My
apologies for not seeing the obvious here.

yes, maybe I should have posted a link to a pastebin service. The problem
in this was that there was no small (less than 100 lines) short program
because the data from which the AoA gets created in the first place is
coming from a largish _DATA_ piece of text - and that is already trimmed to
get a representative piece of the real data.
You really helped me a lot, thanks!
