Not at all. Try the snippet after making mathematicians out of the  
philosopher and ask for evaluation of

  | philosopher mathematicians |
    mathematicians := 2.
    mathematicians := philosopher == mathematicians.
    OrderedCollection new
  	addLast: mathematicians;
  	size

All the sudden the compiler complains (when interactive), why didn't it do  
that earlier for the very same token. Either something is undefined or it  
is not, tertium non datur. Again, this is perhaps *wanted* and I didn't  
know.
