Issue: DESTRUCTURING-BIND (Version 2)

[Jim McDonald <jlm@lucid.com>]

Not to detract from the main point (which I endorse), doesn't
(PROCLAIM '(IGNORE IGNORE)) have most of the desired effect in  
the current language?  

I think treating IGNORE specially is desirable since I see no 
comparable trick to allow duplicate entries in a lambda-list.

(Without a standard, the trick above has the minor danger of
 "capturing" a lamentable use of IGNORE as a normal variable, but
 since you presumably would get a compiler warning, it's not an
 insidious problem.) 

(I suppose one could also introduce an &IGNORE lambda key word, but 
 the thought makes me vaguely uncomfortable.)
