0.8.3.2:
        * SB-SIMPLE-STREAMS:
        ... implement WRITE-SEQUENCE for single channel streams;
        ... fix bug in tests, causing random test failures;
        * add declarations to SCALE-EXPONENT;
        * remove obsolete type declarations in MIX;
        * change type inference for iteration-like variables: if
          interval type is successfuly derived, ignore other inferred
          information.
