I think the module you may be referring to is Data::Dumper, although it tends to format it a little differently. You could have something like:

use Data::Dumper;
...your code here ...
print Dumper($ref);

where $ref is a reference to your data structure, in this case, a hash of arrays.

It's included by default on at least perl 5.6 and above; maybe even earlier versions, so you shouldn't have to install it.
