I'm afraid I know nothing about the module of which you speak, but as to your second question, I'm not quite sure what you expected, but
print "@array"; will stringify the array and print it as a conjoined string i.e. no separators - newlines etc. ... to do that, you'll need to either use
Data::Dumper, Recipe 4.2 from the Cookbook or a version of Recipe 5.5 (also from the Cookbook).
A user level that continues to overstate my experience :-))
