(The behaviour of the String class within the "irb session" is altered) The altered initialize method is now an integral part of the class String. The altered String object behaves as expected (responds to "my_method_test, initialized via redefined initialize method). The String(Literal) object responds to "my_method_test", but it is was not initialized with the redefined initialize method. - The "Literal Instantiation" calls the original (core-C-level) String initialize method instead of the redefined one (user-language-level). This *breaks* the object model. -- http://redmine.ruby-lang.org
