IGNORE, warnings, and &stuff

["Scott E. Fahlman" <Fahlman@C.CS.CMU.EDU>]

    But how about if

    	    (lambda (x &ignore y &ignore z) ...)

    was instead the same as

    	    (lambda (x y z)
    	      (declare (ignore y z))
    	      ...)

I don't see this as any big improvement in convenience over the declare
form we have now.
