Hey, I didn't say that was *all* it's for. It's not on the top of my list of priorities, but I believe that the project will be in a good position to formalize Godel's incompleteness theorem once the main goal is finished. Already we have enough to formalize inductively defined structures like

Norm, thank you for tagging v0.182 as well as merging the pull request. I am getting the impression that this thread has mostly increased your maintenance burden. That's really counter to my intent and needn't be the case! The whole release process on the GitHub side can be made very automatic.
