I believe this is a fairly common pattern for object oriented design.

My experience suggests the opposite. Having an object that you're holding a reference to automagically morph into a different object when a method gets called somewhere else is an anti-pattern. It can lead to situations that are wickedly hard to debug, particularly when you pick up the code six months later, and have forgotten just how clever you were and where.

Title:
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! —

  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
