You might want to mention quasi-quotation as well.  R7RS allows:

   A quasiquote expression may return either newly allocated,
   mutable objects or literal structure for any structure that
   is constructed at run time during the evaluation of the
   expression.

Implementations that provide both this SRFI and immutable quotation
should have quasi-quotation create literal structure, not
mutable objects.
