[Oscar Nierstrasz]

Chris is right. we should take a careful look again at this chapter.

Obviously I missed a lot of inconsistencies while I was editing it.

No.  Chris is right.  A message *send* is an expression.  There are  
other expressions too.

1 + 2 is an expression and it is also a message send.  The message is  
"+ 2", which is not an expression.
