let us say we have a hash of lists that looks like this: 
my $words = {
   'lng'       => ['lang', 'long', 'leng', 'loo'],
   'sentance'  => ['sentence'],
   'thxs'      => ['this', 'thus']
};

and we want to run it through some transform that will give us an array of every single possible combination of words from each family of keys, in this case:
lang sentence this
long sentence this
leng sentence this
loo sentence this
lang sentence thus
long sentence thus
leng sentence thus
loo sentence thus

not neccesseraly in that order, order is unimportant, as long as I had all the possible combinations... what is a good perlish way to do this?
