Hi,

Is there safe way of removing class from system without making
ObsoleteClass? What I found is check whether there're instances of the
class and remove all methods, instance variables and class variables,
and make its superclass as Object, then remove the class and if there's
ObsoleteClass, then I use becomeForward: like this: anObsoleteClass
becomeForward: Object.

I'm not sure my way of removing is correct thing.

Thanks in advance.
