That's an important lesson. No point in overestimating how comfortably
newbies are with the REBOL way of using code. Always focus on the new thing
being explained and include the bare minimum of illustrating code, so as
not to distract the user.

I can imagine ;-). But, you know what, it happens to everyone. Tell me
something, would this have worked for:
++: func ['word] [set word (+ get word 1)]
Less parentheses, but as understandable? For old Scheme or Lisp
programmers, surely. But how does it look to you?
