Luis, Here's the patch as originally sent by James Bielman. It used to work for me, but I've had problems recently. I haven't had time to debug them extensively, but it seems that the lambda list for inverse-translate-objects has changed over time. I would be really interested in a working callback-lambda, at least on SBCL. Unfortunately, I'd also need a way to somehow free/delete unused callbacks later on, so as not to leak memory. --J.
