Got the "default parameters" thing working. Also fixed a nasty "variable not getting initialized" kind of bug while I was at it. That DDD program is saving me lots of time---thanks again GNU/FSF.
I'm putting the tarball online tomorrow or so. No matter how difficult I think something is going to be, just working for a little while makes it better :-).
Ari and I went to see Crouching Tiger, Hidden Dragon today. What a wonderful movie!
