But doesn't DESTRUCTURING-BIND already give us lambda-list processing
for "free"? I mean, it's too lenient with processing the lambda list
because it will allow all kinds of forms ordinary lambda lists won't
allow, but it definitely parses them.

I don't know which software uses this a lot, but I think it's just
very nice to support the general case, if there's support to be
written anyway.
