I have not yet tested it, but I find the writer's arguments in favor of Guile persuasive. I also do not think that using guile is "overkill". I would rather include a powerful scripting language that someone else maintains than reinvent one of our own which we have to add every feature to. If we can resolve the issues Mark raised with this guile implementation, I think we should go ahead with it. I personally would have preferred python, but the author of the guile scripting says python wasn't convenient, and in the absense of my own attempt, I'm inclined to accept his word on it.
