You make it sound as if there was something complex about "self".  Makes 
me wonder whether I am missing something about "self".  As far as I can 
see "self" is an ordinary variable with these additional properties:

  - it is automatically set to the current receiver and it cannot be 
altered by Ruby code

  - it is implicitly used for method invocations without an explicit 
receiver and for instance variable access

Did I miss anything?

Kind regards
