Hi,

> I would be happy to help with reimplementing SystemChangeNotifier using it.
I've actually started this. My plan is that:

 - In the first turn we create SystemChangeAnnouncer which mimics
SystemChangeNotifer workings, and Announcement classes [1] mimicking
AbstractEvents.

 - If this is all done, we replace the SystemChangeNotifier unique
instance with a SystemChangeAnnouncer instance.

 - Finally we start to rewrite SystemChangeNotifier usages, e.g.
breaking up the big #event: methods
to more fine grained subscriptions.

If I am getting anywhere, i'll upload it to the AXAnnouncements repo.
Anybody interested in this? What do you think about the approach?

[1] First stab at the announcement hierarchy combining all changeKinds
with their supportedKinds in AbstarctEvent subclasses:
SystemChanged
  CategoryChanged
     CategoryAdded
     CategoryModified
     CategoryRemoved
     CategoryRenamed
  ClassChanged
     ClassCommented
     ClassDefinitionModified
     ClassModified
     TraitDefinitionModified
     ClassRemoved
     ClassRenamed
     ClassReorganized
     ClassRecategorized
     ClassAdded
  ExpressionChanged
     ExpressionDoIt
  MethodChanged
     MethodAdded
     MethodModified
     MethodRecategorized
     MethodRemoved
  ProtocolChanged
     ProtocolAdded
     ProtocolModified
     ProtocolRemoved
     ProtocolRenamed
