Is there something like this for the entire US Code? Laws in the US are often written to say something like "Amend Section X to say Y.", and it's very hard to follow.
It would certainly be a wonderful resource though. Especially if it could be implemented with a "code review" style interface for showing the votes on each of the bills representing a commit.
I am not sure if there are any for the states.
Eg if motion 39 amend section y to x - Therefore 9.3(iii) is removed and renumber section 9.3, these are the Consequentials and should also be included.
