But, in the next line, "@$self" is syntax for dereferencing an array reference, not a hash reference!

The construct you refer to is called a 'hash slice' -- see perldata#slices.

It assignes the 4 values derived from spliting $STANDINGS{$name} (or the four 0s from the constant) to the the four keys:

qw[ wins places shows losses ]

That one line is (mostly) equivalent to:

$self->{wins} = $STANDINGS[ 0 ] || 0; $self->{places} = $STANDINGS[ 1 ] || 0; $self->{shows} = $STANDINGS[ 2 ] || 0; $self->{looses} = $STANDINGS[ 3 ] || 0;

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

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 How to display code and escape characters are good places to start.
