When I understood the original request correctly, it was the superclasses
which were wanted as a result. The abobe solution gives you the all methods
which bear the name of a message-symbol. Better try:
(classXY allSubclasses add: classXY;yourself) do:
  [:c| c methodDictionary keys includes: #selectorXYZ]
Result is an OrderedCollection of superclasses of classXY which respond to
'selectorXYZ'.
