title: Add method to generated result classes
body: <p>I'm using <code>DBIx::Class::Schema::Loader</code> to generate (and constantly regenerate) result classes from a db schema.</p>
  
  <p>Is there an idomatic way to add methods to the generated classes?</p>
  
  <p>What I currently do is to define the additional methods near the code that's using the result classes:</p>
  
  <pre><code>package Some::Package::Using::Result::Classes;
  use My::Schema::Result::Hello;
  
  ...
  1;
  
  package My::Schema::Result::Hello;
  
  sub str {
    my $self = shift;
    sprintf("Hello: %s, %d", $self-&gt;name, $self-&gt;age);
  }
  1;
  </code></pre>
  
  <p>(As you can see, what I'm trying to do is add a <code>toString()</code>-like function.)</p>
