Jamongkad i think you have to come up with an examples where it's easier to use your library/helper than using 'plain' php.
I think the display_users example is a bad one because you retrieve too much data from the db and you are putting display logic in the controller.
For the numbers example, why would an array with a value 7 return 100?? It has no other use than to show the adding of a conditional argument at runtime.
