The other approach is to avoid letting foreach default to using $_, and avoid passing $_ as an implicit argument (which your code doesn't seem to do, though I suspect you may have meant to open $_ instead of $0). 
    foreach my $element ( @array ) {
        print "\"$element\"\n";
        do_something($element);
    }
An explicit loop variable helps express the code's intention, which helps when some poor fool has to pick up the code six months later.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • 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.
  • Please read these before you post! —
