Problem with setValidity() or resetClass() or ... ?
...tAllSuperClasses(ClassDef)' is called which
## returns "only" 'Class2' (as already 'ClassDef' contains
## only 'Class2') and 'exts' is reduced to exts["Class2"]
## which is then returned.
##
## 'getAllSuperClasses(ClassDef)' calls 'superClassDepth()'
## which don't get "all" but only 'Class2'
## But, for me this seems to be right, since 'ClassDef'
## (in the call) contains only the information about 'Class2'.

superclass (slots are striped). Thus, it is not possible to write validity
method which would perform some checks on children slots.
Say, I want to check if number of slots in a class is equal to "n":
setClass("A", representation(a="numeric", n="integer"),
