As mentioned at the meeting:
* DESTRUCTURING-BIND: http://www.lispworks.com/documentation/lw50/CLHS/Body/m_destru.htm
* Chapters 18. Destructuring and 19. A Query Compiler from On Lisp: http://www.paulgraham.com/onlisptext.html or as HTML: http://www.bookshelf.jp/texi/onlisp/onlisp_19.html#SEC117 http://www.bookshelf.jp/texi/onlisp/onlisp_20.html#SEC120
but I find the styling of the latter unbearable.
