sbcl：defmacro中的马弗风格警告

Question

在sbcl中，我知道在defun中同时使用&可选键和&键时，我可以消除预期的消息，但这似乎在defmacro中不起作用。 （我应该重新设计/重写，我知道，但是这是遗留代码）

当我编译这个文件......

(declaim (sb-ext:muffle-conditions style-warning)) 

(defun wilma (&optional wilma1 &key wilma2 wilma3) 
    (declare (ignore wilma1 wilma2 wilma3))) 

(defmacro betty (&optional betty1 &key betty2 betty3) 
    (declare (ignore betty1 betty2 betty3))) 

......发生这种情况：

home:~/sbcl/experiments/style-warning.d$ sbcl --noinform 
* (compile-file "5.lisp") 

; compiling file "/u/home/sbcl/experiments/style-warning.d/5.lisp" (written 09 OCT 2017 03:31:44 PM): 
; compiling (DECLAIM (MUFFLE-CONDITIONS STYLE-WARNING)) 
; compiling (DEFUN WILMA ...) 
; compiling (DEFMACRO BETTY ...) 
; file: /u/home/sbcl/experiments/style-warning.d/5.lisp 
; in: DEFMACRO BETTY 
;  (DEFMACRO BETTY (&OPTIONAL BETTY1 &KEY BETTY2 BETTY3) 
;  (DECLARE (IGNORE BETTY1 BETTY2 BETTY3))) 
; 
; caught STYLE-WARNING: 
; &OPTIONAL and &KEY found in the same lambda list: (&OPTIONAL BETTY1 &KEY BETTY2 
;              BETTY3) 
; 
; compilation unit finished 
; caught 1 STYLE-WARNING condition 


; /u/home/sbcl/experiments/style-warning.d/5.fasl written 
; compilation finished in 0:00:00.018 
#P"/u/home/sbcl/experiments/style-warning.d/5.fasl" 
T 
NIL 
* (exit) 
home:~/sbcl/experiments/style-warning.d$ 

我如何抑制这些诊断？

编辑1：

由于这是遗留代码，我会只是按摩它SBCL就绪，然后息事宁人，没有理由我不能做这样的事情的任何代码使用它：

home:~/sbcl/experiments/style-warning.d$ sbcl --noinform 
* (with-open-file (*error-output* "/dev/null" :direction :output :if-exists :append) 
(compile-file "5.lisp")) 

; compiling file "/u/home/sbcl/experiments/style-warning.d/5.lisp" (written 09 OCT 2017 03:31:44 PM): 
; compiling (DECLAIM (MUFFLE-CONDITIONS STYLE-WARNING)) 
; compiling (DEFUN WILMA ...) 
; compiling (DEFMACRO BETTY ...) 

; /u/home/sbcl/experiments/style-warning.d/5.fasl written 
; compilation finished in 0:00:00.017 
#P"/u/home/sbcl/experiments/style-warning.d/5.fasl" 
T 
NIL 
* (exit) 
home:~/sbcl/experiments/style-warning.d$ 

但是有什么可以抑制宏定义中的样式警告吗？

您需要之前运行

(declaim (sb-ext:muffle-conditions style-warning)) 

形式(defmacro betty ...)编译。要做到这一点

一种方法是

$ sbcl --non-interactive --eval '(declaim (sb-ext:muffle-conditions style-warning))' --eval '(compile-file "5")' 
This is SBCL 1.4.0, an implementation of ANSI Common Lisp.

; compiling (DEFMACRO BETTY ...) 

; /Users/sds/lisp/5.fasl written 
; compilation finished in 0:00:00.010 

该文件5.lisp只包含wilma和betty：

(defun wilma (&optional wilma1 &key wilma2 wilma3) 
    (declare (ignore wilma1 wilma2 wilma3))) 

(defmacro betty (&optional betty1 &key betty2 betty3) 
    (declare (ignore betty1 betty2 betty3)))
