<<   ((value < 1 or: [value > x1]) or: [value > x2])
        ifTrue: [self error: 'Invalid value'].
  It works, but it looks rather complex. How to do this more "cleanly", 
 with less parentheses? >>

Since Smalltalk has a light weight syntactic protocol, it creates the need 
for "additional" parentheses in certain cases.
I have usually treated complex Boolean expressions as a formatting issue, and 
usually write something like:

    ((value < 1     or: 
    [ value > x1 ]) or: 
    [ value > x2 ]) ifTrue: 
        [self error: 'Invalid value'].

and, of course, there are a lot of suggestions from others that preceded this.

Cheers,
Jerry.
