Ok, this wording is now on-line, thanks.

Also, I noticed I inadvertently  swapped the traits and parent0 labels
in the drawing about deriving objects  :-( If z derives from x, then z
traits traits == x traits  traits == Traits traits. This mistake seems
to  have  caused  some  confusion  (according  to  the  IRC  logs).  I
apologize. A fixed version is on-line.

Well, it  is always  nice to get  thanks, but  the tutorial is  a very
little piece of work compared to  all the thoughts and efforts Lee and
Brian put (and continue to put) into Slate. They deserve to be thanked
much more than I do.
