Said expression is a constructor of a String which will return a different String instance on every evaluation. "Depending upon the data type of the object, a variable is a name for the object itself or a reference to it." In an introductory text I would not _start_ with this statement. Better: "A variable is a place that stores a reference to an object." Same for your treatment of "immediate values". This is really an implementation detail which should be taught much later. I think it helps understanding if one does _not_ bring this up that early. Actually, from a point of view of the user of the language it does not matter _at all_ (only for performance, but not functionality wise). "If the method were not found in String, Ruby would have followed the superclass (sc, green arrow) links in search for the method definition." and "It creates a new anonymous class object and inserts it into Foo=92s superclass chain!" This is not true. The chain of classes and modules found via Module#ancestors is traversed instead. There is no need for a new anonymous class. The only place where new classes are automatically allocated is the singleton class of an instance. I stopped reading there as I found your diagram about singleton quite complicated and unclear.
