As I&#8217;ve <a href="http://andthennothing.net/archives/2004/11/17/holub-on-patterns">mentioned</a>, I need to look into patterns again. I think that I grasp the main rationale behind the pattern, and its benefits. It might be a occupational injury since we use C++ at work, where normally adding interfaces breaks binary compability, but I feel a resistance towards adding an interface that adds little value, no real behaviour. Hmm, I wonder if it&#8217;s a useful pattern or just complicates things (hopefully I&#8217;ll know if I get around to read <a href="http://andthennothing.net/archives/2004/11/17/holub-on-patterns">Holub on Patterns</a>).</p>
