Re: Reviving an old discussion about IGNORE

LOOP has always been a bit peculiar. I had forgotten that args named IGNORE was
not common lisp, but even so it always seemed odd (and somehow illegitimate) that
you used NIL for arguments or pattern elements in LOOP that you wanted to ignore.
LOOP is just using ZL:DESTRUCTURING-BIND, which treats NIL as an empty
list of variables, not a variable named NIL, and ignores values that
match up with it.
