Reverting to draft until the FIP etc

Reverting this to draft and awaiting a new FIP to specify it.

We did #605. This only checks expectations though, not state invariants.

I'm on the fence about checking spelling, but game to try it as experiment. However I'm pretty confident that more general language linting will be a huge distraction from actual...

This will only actually print anything for failed tests, right?

#197 , #214 does a heap of the work for this (not yet merged, needs stewardship)

I've spent some time investigating how to improve things here, but it turns out to be quite complex. In our current situation we have: - A pattern of `[Result].map_err(|e| e.downcast_default(...))`...

External iterators would be great. And then we could "give up" on doing better than "illegal state" for remaining hard cases. Your proposal re aborting sounds reasonable, and could clean...
