Well, now I am curious as to why the "all" form evaluates BOTH

Hell yes!
Using `or` to run functio
So I was surprised I did not get more feedback on my abused coroutine,
maybe that is good or bad, not sure.
Any ways I am on to trying to make that coroutine act more like the
State Pattern from Gang of Four. And well reading this:
