We don't provide interface databases that include new Leopard stuff (like NSGradient, for example).

At some fairly near future date, we might want to build interfaces with -mmacosx-version-min=10.5 or come up with some scheme to allow the user to switch between various versions.

Clozure Common Lisp seems to be too eager in its checking of congruency of generic function lambda lists and those of their methods.

Consider the following example:

? (defgeneric foo (a b c))
#<STANDARD-GENERIC-FUNCTION FOO #x30004125B93F>
? (add-method
   #'foo
   (make-instance 'standard-method
     :qualifiers '()
     :specializers (list (find-class 't) (find-class 't) (find-class 't))
     :lambda-list '(a b c)
     :function (lambda (&rest args) (print args))))
> Error: Lambda list of method #<STANDARD-METHOD NIL (T T T)>
>        is incompatible with that of the generic function FOO.
>        Method's lambda-list : (A B C)
>        Generic-function's   : (A B C)

While executing: CCL::CHECK-DEFMETHOD-CONGRUENCY, in process  
listener(1).

Indeed, check-defmethod-congruency uses the method-function to check for congruency, while it should actually use method-lambda-list for that purpose (at least in non-standard cases).

As far as I can tell at the moment, this is the only remaining step so that I can provide compatibility in Closer to MOP of the generic function invocation protocol to the specification in AMOP.

There's a Trac contrib script that can be used as an svn post-commit-hook which will look through the commit log for references to tickets and update the tickets automagically. This would be a handy feature.
