 ruby_class : it's in the source, this mean that it's documented :-)

 Well a class can be seen as an object or as a class, i.e. with a class
 you can define a singleton method or a method.

 #instance_eval work with any object, and in this case a class is just an
  object like any other and def will define a singleton method

 #class_eval work only with classes (and modules) and in this case def will
  define instance methods.
