Subject: Traversing superviews' class instance variables

I have certain variables that are 'properties' and I keep track of them in a 
class instance variable called @fields, and each subclass may have it's own 
fields.  I want to navigate through the hierarchy and go through each list, is 
something like this possible?:

class View
   @fields = [:origin]
   def View.fields()
     super.fields()
     @fields
   end
   attr :origin
end

class Button < View
   @fields = [:caption]
   attr :caption
end

View.fields() actually finds :cation when I do Button.fields(), but super does 
not work.  Or maybe there is another way to do this?


Thanks,
Mike
