Getters And Setters are Evil

Setters are evil because they allow you to have inconsistent objects, which they cannot work until they have set their collaborators (see PicoContainer/Good Citizen).

Getters are evil because they allow you to extract the data from the object, instead of putting the action where the data is. (see violating encapsulation, or Martin Fowler's "GetterEradicator").

So everything goes round and back to Allen Holub: "Why getter and setter methods are evil".
