/**
 * Kotlin examples of following/violation Law of Demeter LoD (a.k.a. Principle of Least Knowledge PoLK)
 *  
 * Law of Demeter for functions requires that a method m of an object O may only invoke the
 * methods of the following kinds of objects:
 * 1. O itself
 * 2. m's parameters
 * 3. Any objects created/instantiated within m
 * 4. O's direct component objects
 * 5. A global variable, accessible by O, in the scope of m
