Subject: inheritence of aliases methods - suprise!


this suprised me today:

     harp:~ > cat a.rb
     class A
       def assertion
         raise NotImplementedError
       end
       alias_method "assertion?", "assertion"
     end

     class B < A
       def assertion
         true
       end
     end

     B::new.assertion?


     harp:~ > ruby a.rb
     a.rb:3:in `assertion?': NotImplementedError (NotImplementedError)
             from a.rb:14


this only way i can seem to make this work is through some self::inherited
hacks or to actually define assertion? in the base class.  is there no clean
way to inherit aliases?

regards.
