Obviously that would be "self ->class<- addInstVarName: 

BTW, you do realize that you can try all of this right in the browser, 
no? All you need is to go to class SmallInteger and edit the class 
definition. Then you can see whether it is possible to add instance 
variables (it's not), class variables (works fine), or class instance 
variables (works fine, too). And once you've tried this it should be 
pretty obvious that your code is broken and not the VM and/or ClassBuilder.
