Is there any existing (or previously proposed) way of 'scoping' the  
behavior
of private?  I'm thinking something like:

class A
   attr_accessor :a
   private {
     attr_accessor :b
   }
end

I'm aware that you can 'toggle' visibility:

class A
   attr_accessor :a   # public
   private
   attr_accessor :b   # private
   public
   attr_accessor :c   # public
end

but it would seem some sort of block/scope notation would be cleaner.
