You keep saying method_missing is "bad" but what exactly is so bad about it?
The main complaint about method_missing has always been the inefficiency. The class hierarchy is walked every single time and only then is method_missing called. The use of define_method is a pretty neat solution to that problem. The method that wasn't found gets defined and it doesn't rely on method_missing again. Like a cache.
