Actually useful 'unsolved meta' error message

See original GitHub issue

I guess we’re gonna add a stack to Zonker

I think we can only show these instead of all:
Error: Unsolved meta t'
           in `t'`
           in `value-inv {t'}`
           in `value-inv {t'} {_}`
What’s the exact criteria?
Users can know how to make the code pass IMO

Well, it might be that the meta is the last argument of a huge application. There will be many edge cases I believe
