Slightly OT perhaps, but the freely available chapter 9 of Perl Best Pratices (PDF) recommends:
Use a hash of named arguments for any subroutine that has more than three parameters. Named arguments should always be passed to a subroutine inside a single hash, like so:
sub padded { my ($arg_ref) = @_; my $gap = $arg_ref->{cols} - length $arg_ref->{text}; my $left = $arg_ref->{centered} ? int($gap/2) : 0; my $right = $gap - $left; return $arg_ref->{filler} x $left . $arg_ref->{text} . $arg_ref->{filler} x $right; }
# and then...
for my $line (@lines) { $line = padded({ text=>$line, cols=>20, centered=>1, filler=>$SPAC +E }); }

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! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
