# A module describes the capabilities of a group of objects, ie what data it has
|
|
# and functions it responds to.
|
|
# The group may be a Class, but a module may be included into classes and objects too.
|
|
#
|
|
# The class also keeps a list of class methods (with names+code)
|
|
# Class methods are instance methods on the class object
|
|
|
|
# So it is essential that the class (the object defining the class)
|
|
# can carry methods. It does so as instance variables.
|
|
# In fact this property is implemented in the Object, as methods
|
|
# may be added to any object at run-time
