But an example of where it becomes powerful in Rails is the has_many and belongs_to associations. If you add has_many :employees to a Company model, Rails knows to respond to company.employees and company.employees= Another example is the ruby Flickr API - it uses method_missing to convert the API endpoints to Ruby methods.

Why would I not just call m.find('name', 'madpilot') like you did in the first example? How does having a missing method help me as a user of your API?
