Jeffrey and Jeff,

Thank you for clearing this up.

The problem was that I didn't read page 47 of the guide carefully. The 
introduction of the <<- operator on page 44 leaves
me with the impression that <<- will create an assignment in the local 
environment THAT ALSO holds true for the next
higher environment.
