I was hoping on the content. Life is not simple for an apprentice. :-( ;-)

References are like boxes. If you take a picture of them,
you get just that: the box. To get to the content, you
first have to open them. It's the same with references.
If you print them, you just get that: some kind of 'spooky'
representation of the reference. To get to the content, open
it. For references pointing to arrays, you do that by placing
a @ in front of the reference. So, for instance:
print "@$array_ref\n";
