That's because R5RS punts on a precise description of the connection
between datums and external representations. In the place where it
matters most, namely the description of `quote', the confusion is
especially apparent. Whether it's harmless is a matter of judgement,
I guess, but I've sure always found it pretty serious, especially when
showing it to people not already familiar with Lisp or Scheme lore.
