We use this pattern in Mondrian scripts, Glamour scripts, and in Moose scripts for navigating models. However, we are most of the times doing it with other Symbol selectors. For example: - in Mondrian, we use moValue: - in Glamour, we use glamourValue: Using dedicated extensions enable us to control the kinds of semantics we want in the scripting. For example, the glamourValue: is different from moValue:. Cheers, Doru On 30 Oct 2010, at 22:56, Andres Valloud wrote:

I agree with this, polymorphism is awesome. For instance, something I did with Assessments was to make objects polymorphic with classes. This device allows Assessments to run SUnit tests without needing to touch any of the test case classes (you can just create pseudo-classes that pretend to be the classes you need but can't have). And you get to implement #new on the instance side :).
