I disagree that Clojure's AST changes are gratuitous. Rich has repeatedly provided his reasons for them. You may think they are bad reasons, but it's not like he just said "ZOMG there are too many parens!"

That being said, I tend to use destructuring in common-lisp, and if you are taking an element from a collection by using c*r then you are probably doing it wrong.

Optima has more complete support for destructuring, but this works just fine in CL with out any libraries:

    (let ((some-plist '(:foo 1 :bar 2)))
      (destructuring-bind (&key foo &allow-other-keys) some-plist
        foo))
