* fixed bugs in other functions taking environment objects, allowing
calls with an explicit NIL environment argument to be compiled
without error.
+ * fixed bug 228: primary return values from
+ FUNCTION-LAMBDA-EXPRESSION are either NIL or suitable for input to
+ COMPILE or FUNCTION.
+ * fixed a bug in DEFSTRUCT: predicates for :NAMED structures with
+ :TYPE will no longer signal errors on innocuous objects.
+ * fixed bug 231b: SETQ is better at respecting type declarations in
+ the lexical environment.
+ * fixed a bug in DEFCLASS: classes named by symbols with no or
+ unprintable packages can now be defined.
* fixed some bugs revealed by Paul Dietz' test suite:
** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
not just nonnegative fixnums;
+ ** the logical bit-array operators such as BIT-AND now accept an
+ explicit NIL for their "opt-arg" argument (to indicate a
+ freshly-consed result bit-array);
planned incompatible changes in 0.7.x:
* (not done yet, but planned:) When the profiling interface settles
