+
+       This set of patches eliminates the dependency between the
+       implementation of evaluator specific memoization codes and special
+       constants like #f, '() etc. ('flags'), which are not evaluator
+       specific.  The goal is to remove definitions of evaluator
+       memoization codes completely from the public interface.  This will
+       make it possible to experiment more freely with optimizations of
+       guile's internal representation of memoized code.
+
+       * objects.c (scm_class_of): Eliminate dependency on SCM_ISYMNUM.
+
+       * print.c (iflagnames): New array, holding the printed names of
+       guile's special constants ('flags').
+
+       (scm_isymnames): Now holds only the printed names of the
+       memoization codes.
+
+       (scm_iprin1): Separate the handling of memoization codes and
+       guile's special constants.
+
+       * tags.h (scm_tc9_flag, SCM_ITAG9, SCM_MAKE_ITAG9, SCM_ITAG9_DATA,
+       SCM_IFLAGNUM): new
+
+       (scm_tc8_char, scm_tc8_iloc, SCM_BOOL_F, SCM_BOOL_T,
+       SCM_UNDEFINED, SCM_EOF_VAL, SCM_EOL, SCM_UNSPECIFIED, SCM_UNBOUND,
+       SCM_ELISP_NIL, SCM_IM_DISPATCH, SCM_IM_SLOT_REF,
+       SCM_IM_SLOT_SET_X, SCM_IM_DELAY, SCM_IM_FUTURE,
+       SCM_IM_CALL_WITH_VALUES, SCM_IM_NIL_COND, SCM_IM_BIND): Changed
+       values.
+
+       (SCM_IFLAGP): SCM_IFLAGP now only tests for flags.
+
+       (SCM_IFLAGP, SCM_MAKIFLAG, SCM_IFLAGNUM): Generalized to use the
+       tc9 macros and scm_tc9_flag.
