The current DESTRUCTURING-BIND could be much more useful if you could pull apart objects and arrays.  CoffeeScript has a great mechanism for this (http://coffeescript.org/#destructuring).  Below is an example of what this macro might look like in parenscript.  Let me know your thoughts.

(d-bind (:obj name (:obj firstname lastname)

              likes (:arr first-like second-like))

        (create :name (create :firstname "Joe" :lastname "Blo")

                :occupation "Web Developer"

                :likes '("programming" "woodworking" "cycling"))

        (alert (+ "Your name is " firstname " and you like " first-like)))
