Hi Marcus,

I think I just found a workaround:
if you make Slot>>isVirtual to return true by default and override it in InstanceVariableSlot to return false the problem will be gone

Yes, that should be done. 

I don't want to subclass InstanceVariableSlot because it becomes impossible to see definition of class with slots in Browser and as soon as I add new instvars all old ones become default InstanceVariableSlot and not my custom.

Yes, I will fix that one, too. Because it can be nice to just subclass that one��� but people need to then know about byte code and change the emit* methods, too.

Therefore the first step:

This is now in 40457 

#isSpecial is fixed, too.

This means that you can subclass AbstractInstanceVariableSlot and just override #read and #write:to: and it should work.

To get more performance, later you should look into #emitStore: and #emitValue:
