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.

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).
