I've learned a little bit more about the release schedule and have 
realized that I should be very careful about changes like that right 
now. (in particular, the last one involves changing things outside of 
src/optional/python-bindings ). I get the impression that this kind of 
thing shouldn't be done in trunk until after 2.4 is branched off.

So, I'm going to keep my focus on config/build issues, bugs, 
documentation, and making sure the api can be used in an OO style.
