XOTcl Object System

• All classes have a common root class (::xotcl::Object)
• The behavior (methods) of the common root class is inherited to all other classes
• Methods can be added at any time using the methods "proc" and "instproc"
  
• XOTcl classes are as well Objects, instances of a meta-class ::xotcl::Class
• As a class provides methods to objects, a meta-class provides methods to classes
