+237: "Environment arguments to type functions"
+  a. Functions SUBTYPEP, TYPEP, UPGRADED-ARRAY-ELEMENT-TYPE, and 
+     UPGRADED-COMPLEX-PART-TYPE now have an optional environment
+     argument, but they ignore it completely.  This is almost 
+     certainly not correct.
+  b. Also, the compiler's optimizers for TYPEP have not been informed
+     about the new argument; consequently, they will not transform
+     calls of the form (TYPEP 1 'INTEGER NIL), even though this is
+     just as optimizeable as (TYPEP 1 'INTEGER).

+238: "REPL compiler overenthusiasm for CLOS code"
+  From the REPL,
+    * (defclass foo () ())
+    * (defmethod bar ((x foo) (foo foo)) (call-next-method))
+  causes approximately 100 lines of code deletion notes.  Some
+  discussion on this issue happened under the title 'Three "interesting"
+  bugs in PCL', resulting in a fix for this oververbosity from the
+  compiler proper; however, the problem persists in the interactor
+  because the notion of original source is not preserved: for the
+  compiler, the original source of the above expression is (DEFMETHOD
+  BAR ((X FOO) (FOO FOO)) (CALL-NEXT-METHOD)), while by the time the
+  compiler gets its hands on the code needing compilation from the REPL,
+  it has been macroexpanded several times.

+  "DEFCLASS mysteriously remembers uninterned accessor names."
+  (from tonyms on #lisp IRC 2003-02-25)
+  In sbcl-0.7.12.55, typing
+    (defclass foo () ((bar :accessor foo-bar)))
+    (profile foo-bar)
+    (unintern 'foo-bar)
+    (defclass foo () ((bar :accessor foo-bar)))
+  gives the error message
+    "#:FOO-BAR already names an ordinary function or a macro."
+  So it's somehow checking the uninterned old accessor name instead
+  of the new requested accessor name, which seems broken to me (WHN).
