DEFINE-METHOD-COMBINATION bugs

[Nikodemus Siivola]

  (reported by Bruno Haible via the clisp test suite)

  a. Syntax checking laxity (should produce errors):
     i. (define-method-combination foo :documentation :operator)
    ii. (define-method-combination foo :documentation nil)
   iii. (define-method-combination foo nil)
    iv. (define-method-combination foo nil nil
         (:arguments order &aux &key))
     v. (define-method-combination foo nil nil (:arguments &whole))
    vi. (define-method-combination foo nil nil (:generic-function))
   vii. (define-method-combination foo nil nil (:generic-function bar baz))
  viii. (define-method-combination foo nil nil (:generic-function (bar)))
    ix. (define-method-combination foo nil ((3)))
     x. (define-method-combination foo nil ((a)))

  b. define-method-combination arguments lambda list badness
     i. &aux args are currently unsupported;
    ii. default values of &optional and &key arguments are ignored;
   iii. supplied-p variables for &optional and &key arguments are not
        bound.

  c. (fixed in sbcl-0.9.15.15)
