Currently you cannot override the generated methods and access super ie:

```ruby
monetize :price_cents

def price=(value)
   # stuff
   super # NoMethodError
end
```

This happens because the method is defined on the class directly so their is no super method to call. A solution today is to create an alias (`alias :old_price= :price=`) before overriding the method as is recommending in issue RubyMoney#507.

Instead, a new module can be created, included into the class, and the methods defined on it allowing `super` to work as expected.
