zodiac:syntax-null?

• (zodiac:syntax-null? sexp) -> zodiac:read
      sexp : (union zodiac:list zodiac:improper-list)

  Tests to see if the syntax is ``null''. The read-object accessors should not be used to access them. Instead use these procedures: zodiac:syntax-car, zodiac:syntax-cdr, zodiac:syntax-null? , and zodiac:syntax-map.

  Use zodiac:structurize-syntax to get the effect of a zodiac:syntax-cons.
