Subject: alias_method 'stickiness'


any idea if this behaviour is intended or not?

   # the problem
   #
     module NRT
       class Subscription
         def process_incoming
           raise NotImplementedError
         end
         alias_method "run", "process_incoming"
       end
       class OLSSubscription < Subscription
         def process_incoming
           p 42
         end
       end
     end
     begin; NRT::OLSSubscription::new.run ;rescue Exception => e; p e; end

   #
   # an easy solution

     module NRT
       class Subscription
         def self::anonym dst, src
           module_eval %Q[ def #{ dst }(*a, &b) #{ src }(*a, &b) end ]
         end
         anonym "run", "process_incoming"
       end
     end
     NRT::OLSSubscription::new.run
