Not really. You can use ClassVariables though. Here's an example for Sets:
Object subclass: #MyClass instanceVariableNames: '' classVariableNames: 'MyClassVar' package: 'MyPackage' MyClass class>>initialize super initialize. MyClassVar := Set new. MyClass>>foo self bar: MyClassVar Obviously sets are not as easy to deal with. You cannot mutate empty arrays/bytearrays, if you concatenate something it creates a new object. You can add things in sets. So you need to be careful... You can make the object read-only to avoid issues (MyClassVar beReadOnlyObject).
