The behavior you observe is to be expected, if one is sufficiently familiar with Perl 5.

In particular none of the steps cause a copy of the array (hey, you're passing a reference after all!).

Perhaps the most surprising point is that foreach my $item alises $item to the current list/array element. But again that's "works as designed".

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
