When you do use reload! it pretty much means that you can’t use  
anything you wrote before you ran reload!. Reload effectively guts  
Activerecord classes, so if you have say an instance of Person and  
reload! then that instance remains an instance of the old Person  
class, but that class has had all its methods removed and so is a bit  
useless.
