 Well, when you use keywords (like `def' 'alias') ruby use the
 "current" class to know where it must define the method.

 With #instance_eval, the current class is the singleton class and ruby
 will define singleton methods

 With #module_eval, the current is the class (i.e. self) and ruby define
 instance methods.

 By default, #class_eval is the same than #module_eval
