Hi. I'm looking for some good short/lightning talks for the International Lisp Conference 2009 (March 22-25 at MIT in Cambridge, MA, USA; see ilc09.org). If you, or anyone who you think might be coming to the conference, might have a short talk to give, please send me a brief description. Please for...

I suggest asking Franz's support people. As long as you're paying for Allegro, you might as well take advantage of the fact that there's a company behind the product.

Just don't specify an element type. Then the array elements can hold any Lisp object.

(It's better not to use the word "pointer" when talking about Lisp, I've found.)

Peter Seibel gave a lecture at Google where he showed a simple example of a DSL in Lisp. http://video.google.com/videoplay?docid=448441135356213813 Shriram Krishnamurthy of Brown has a slide presentation showing a finite-state machine done nicely as macros. (It's Scheme but it's all the same idea.) ...

Although it does not work to have a macro that expands directly into a (declare ...),
you can do this kind of thing:

(defmacro with-dcl (var &body body)
`(let ((,var 0))
(declare (fixnum ,var))
,@body))

At ITA Software, we use SBCL for one large project, and CCL for one even larger project. One constraint at ITA is that we are committed to using open source implementations. We switched from CMUCL to SBCL somewhat before I joined the company (three years ago). These two implementations are closely r...
