Sorry, that was supposed to read as follows in order to make a bit more
sense in my argument:

  One problem with this is that it creates mutual references between
  sections 7.1.1, which describes the lexical structure _as_a_stream_of
  _tokens_, and 7.1.2, which describes the external representation of
  S-expressions -- in terms of the stream of tokens.
