A method is a routine that is associated with an object or class.
self identifier
Inside method definitions the special identifier self is available.
In static or class methods it identifies the object/class type itself.
In instance methods self identifies the very instance.
However, since static class methods are just “global” routines within the type's namespace, such methods do not know the self identifier.
