The problem is that the class as an Object is registered with the startup
logic. (someone called
"Smalltalk addToStartUpList:" at some point in the past).
This could be detected, a safe delete would check for: References, subclasses,
instances and
and known pointers like this.
But in general, using reflection will give you situations where static analyis
fails.
e.g.
(Smalltalk classNamed: 'Obj', 'ect')
is a use of Object, but hard to detect, especially if the string is the result
of some real computation.
