Thanks, guys.  
I was thinking of reserved words in the sense that normal procedural languages 
use the term, as in C's  "if", "else", etc.  In this strict sense the 
pseudovariables that are actually instances of a class don't count.  Are self 
and super also some kind of objects or merely syntactical tokens.  I seem to 
remember sending both messages.
