+Extending a class ~
+							*extends*
 A class can extend one other class. *E1352* *E1353* *E1354*
+The basic idea is to build on top of an existing class, add properties to it.
+
+The extended class is called the "base class" or "super class".  The new class
+is called the "child class".
+
+Object members from the base class are all taken over by the child class.  It
+is not possible to override them (unlike some other languages).
+
+						*E1356* *E1357* *E1358*
+Object methods of the base class can be overruled.  The signature (arguments,
+argument types and return type) must be exactly the same.  The method of the
+base class can be called by prefixing "super.".
+
+Other object methods of the base class are taken over by the child class.
+
+Class functions, including functions starting with "new", can be overruled,
+like with object methods.  The function on the base class can be called by
+prefixing the name of the class (for class functions) or "super.".
+
+Unlike other languages, the constructor of the base class does not need to be
+invoked.  In fact, it cannot be invoked.  If some initialization from the base
+class also needs to be done in a child class, put it in an object method and
+call that method from every constructor().
+
+If the base class did not specify a new() function then one was automatically
+created.  This function will not be taken over by the child class.  The child
+class can define its own new() function, or, if there isn't one, a new()
+function will be added automatically.
