I actually have a replacement for CEE on my short term todo list. In
addition to not being hopelessly broken, it splits the dataflow fact
analysis out from the transformation pass, so it will probably be more
useful to you than CEE is.
My short-term spare-time priority list is:
1) finish the tutorial
2) finish legalizedagtypes.
3) finish the cee replacement.
