* the compiler is now aware that SYMBOL-FUNCTION returns a FUNCTION
and that READ-DELIMITED-LIST returns a LIST. (thanks to Robert
E. Brown and Tony Martinez respectively)
+ * PCL is now smarter about SLOT-VALUE, (SETF SLOT-VALUE) and
+ SLOT-BOUNDP: in particular, it is now able to optimize them much
+ better, and is now not vulnerable to having packages renamed.
+ Furthermore, a compliance bug has been fixed: SLOT-MISSING is now
+ always called when a slot is not present in an instance. (thanks
+ to Gerd Moellmann)
* fixed some bugs revealed by Paul Dietz' test suite:
** ARRAY-IN-BOUNDS-P now allows arbitrary integers as arguments,
not just nonnegative fixnums;
