Yes, I noticed that I was still getting errors, but good that you fixed it. I'm cleaning up the parts of the code I've been working on the most including some of the code in cpp.py.Great. I think we should try to finish up a release of FFC 0.9.1 before the end of February. Ideally, we should go through all the code again and remove all FIXMEs. Then FFC will be in ridiculously good shape.
Agree, I think that it sounds like a good idea. Kristian
