- In sbcl-0.7.3.11, compiling the (illegal) code
- (in-package :cl-user)
- (defmethod prove ((uustk uustk))
- (zap ((frob () nil))
- (frob)))
- gives the (not terribly clear) error message
- ; caught ERROR:
- ; (during macroexpansion of (DEFMETHOD PROVE ...))
- ; can't get template for (FROB NIL NIL)
- The problem seems to be that the code walker used by the DEFMETHOD
- macro is unhappy with the illegal syntax in the method body, and
- is giving an unclear error message.

- (reported by Tony Martinez sbcl-devel 2004-05-23)
- When CHECK-TYPE signals a TYPE-ERROR, the TYPE-ERROR-DATUM holds the
- lisp symbolic place in question rather than the place's value. This
- seems wrong.

-338: "MOP specializers as type specifiers"
- (reported by Bruno Haible sbcl-devel 2004-06-11)
-
- ANSI 7.6.2 says:
- Because every valid parameter specializer is also a valid type
- specifier, the function typep can be used during method selection
- to determine whether an argument satisfies a parameter
- specializer.
-
- however, SBCL's EQL specializers are not type specifiers:
- (defmethod foo ((x (eql 4.0))) 3.0)
- (typep 1 (first (sb-pcl:method-specializers *)))
- gives an error.

339: "DEFINE-METHOD-COMBINATION bugs"
(reported by Bruno Haible via the clisp test suite)
should signal an invalid-method-error, as the :IGNORE (NUMBER)
method is applicable, and yet matches neither of the method group
qualifier patterns.

+
+341: PPRINT-LOGICAL-BLOCK / PPRINT-FILL / PPRINT-LINEAR sharing detection.
+ (from Paul Dietz' test suite)
+
+ CLHS on PPRINT-LINEAR and PPRINT-FILL (and PPRINT-TABULAR, though
+ that's slightly different) states that these functions perform
+ circular and shared structure detection on their object. Therefore,
+
+ a.(let ((*print-circle* t))
+ (pprint-linear *standard-output* (let ((x '(a))) (list x x))))
+ should print "(#1=(A) #1#)"
+
+ b.(let ((*print-circle* t))
+ (pprint-linear *standard-output*
+ (let ((x (cons nil nil))) (setf (cdr x) x) x)))
+ should print "#1=(NIL . #1#)"
+
+ (it is likely that the fault lies in PPRINT-LOGICAL-BLOCK, as
+ suggested by the suggested implementation of PPRINT-TABULAR)
+
+342: PPRINT-TABULAR / PPRINT-LOGICAL-BLOCK logical block start position
+ The logical block introduced by PPRINT-LOGICAL-BLOCK should not
+ include the prefix, so that
+ (pprint-tabular *standard-output* '(1 2 3) t nil 2)
+ should print
+ "(1 2 3)" rather than "(1 2 3)".
+
+343: MOP:COMPUTE-DISCRIMINATING-FUNCTION overriding causes error
+ Even the simplest possible overriding of
+ COMPUTE-DISCRIMINATING-FUNCTION, suggested in the PCL implementation
+ as "canonical", does not work:
+ (defclass my-generic-function (standard-generic-function) ()
+ (:metaclass funcallable-standard-class))
+ (defmethod compute-discriminating-function ((gf my-generic-function))
+ (let ((dfun (call-next-method)))
+ (lambda (&rest args)
+ (apply dfun args))))
+ (defgeneric foo (x)
+ (:generic-function-class my-generic-function))
+ (defmethod foo (x) (+ x x))
+ (foo 5)
+ signals an error. This error is the same even if the LAMBDA is
+ replaced by (FUNCTION (SB-KERNEL:INSTANCE-LAMBDA ...)). Maybe the
+ SET-FUNCALLABLE-INSTANCE-FUN scary stuff in
+ src/code/target-defstruct.lisp is broken? This seems to be broken
+ in CMUCL 18e, so it's not caused by a recent change.
