‘some\_object.class.to\_s’ doesn’t work because it returns the entire  
hierarchy,  
i.e ‘SomeModule::SomeClass’. I could do some string ops on that but it  
seems  
there would be an easier way. Here’s an example:

class MenuStyle  
class Button \< Style  
end  
end

class View  
def initialize()  
@delegate = MenuStyle.const\_get( self.class.to\_s )  
end  
end

Thanks,  
Mike

   def klass_stamp(hierachy, *a, &b)
     ancestors = hierachy.split(%r/::/)
     parent = Object
     while((child = ancestors.shift))
       klass = parent.const_get child
       parent = klass
     end
     klass::new(*a, &b)
   end
