Comment #3 on issue 3648 by marianopeck: A "Stratified" proxy in smalltalk http://code.google.com/p/pharo/issues/detail?id=3648 Hi Igor. I remember you showed me this implementation once I was asking about how to do proxies for classes. It works, but there is something I don't like: having to do the shallow copy of the class. createHandler " This method will create a handler - an anonymous class, which will receive the #handleMessage:forProxy: message. To get a proxy object, you must instantiate a handler instance by sending #basicNew to it. See my subclasses for examples " ^ self shallowCopy methodDict: nil; superclass: self I don't like that because for EACH proxy, I have to instantiate a new class (an object with a lot of intsVars) and an instance of that class. In my case, I want to create a lot of proxies and the memory is important, so that solution doesn't scale. What we did is to use the same proxy as the metaclass. So we defined for example: ProtoObject subclass: #ClassProxy instanceVariableNames: 'superclass methodDict format fileName' classVariableNames: '' poolDictionaries: '' category: 'Proxies' ClassProxy >> initialize super initialize. superclass := ProxySuperclass. methodDict := nil. fileName := nil. ProxySuperclass >> cannotInterpret: aMessage ^ ClassProxyHandler mareaHandleCannotInterpret: aMessage for: aMessage lookupClass receiver: self Anyway, if you are interested, take a look to the package Proxies in http://www.squeaksource.com/Marea
