@$self->{ITEMS} @$x->{y}

$self->{ITEMS} (or $x->{y}) returns a reference or pointer to an array of values. The @-operator dereferences it to be used by the map and grep functions.

This could have been much more clearly written as:

@{ $x->{y} }

But if wishes were fishes... :) My point is that there's nothing magical about this, and doesn't really require an "examination."

Hope this helps, or at least makes sense with all that chaos out there.

I am the lurker that spams in the night.

(UPDATE: I understand what chip is saying, and I'm not trying to be a smartass. I think he's reading into the code a little too deeply. Just wanted to clarify things for some of the less experienced readers. :P)

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

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
