load-program* was what I needed. Still not entirely sure why that works for me and include-program* doesn't seem to... oh well. Maybe next weekend I'll just make a (big) pot of coffee and and go through all of snow.scm's code and try to understand it better. For now, I have it doing what I needed.
As for pregexp, I still havn't heard back from Dorai. I'll give it about a week, if I still havn't gotten a response I'll just go ahead and upload what I have with something like (license: see-COPYING). Will that be OK?
