Sean, I am not an expert in Pharo, but I think you should try subclassing ProtoObject... Joachim Am 31.03.2015 18:51 schrieb "Sean P. DeNigris" <sean@clipperadams.com>:

From "Design Patterns" pg. 215:

    You can make[8] generic proxies in Smalltalk by defining classes whose superclass is nil and defining the doesNotUnderstand: method to handle messages.

    [8] Almost all classes ultimately have Object as their superclass. Hence this is the same as saying "defining a class that doesn't have Object as its superclass."

but in Pharo:     nil subclass: #MyProxy instanceVariableNames: '' classVariableNames: '' category: '' -> MessageNotUnderstood: receiver of "subclass:instanceVariableNames:classVariableNames:category:" is nil
