It's interesting, this is how I write them too. But I noticed lodin's node, which contains an important but subtle difference; by doing this:
sub field { my $self = shift; $self->{field} = $_[0] if @_; ... }
instead of this:
sub field { my ($self,$val) = @_; $self->{field} = $val if defined $val; ... }
you don't run into issues where $self->field(undef) would silently return the old value without changing it, which isn't what you might expect. But because I've seen the second form elsewhere and it's technically better practice to assign @_ to variables I just stuck with it, but clearly the first way is better.

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.
