And you should *really* only use this in tests :-)</div>

Uhh! This feels like JavaScript ... :o) I would rather work on improving Squeak's meta-object protocol and with it class construction and refinement. Especially for tests. Let's not undermine the idea of having classes in Smalltalk.

<div>Objects in Squeak/Smalltalk are quite dynamic already. That name is misleading. :-)</div>

<p>Did we already have something like this for Squeak? May this become a pattern for situations where you actually don't need a class (e. g., when writing very small mock objects for tests)?</p>
