`mueval` imports some modules by default (see https://github.com/gwern/mueval/blob/master/Mueval/Context.hs#L24-L93), incurring a *runtime* dependency on several packages (as far as I can see, those packages are `show`, `simple-reflect`, `QuickCheck`, `pretty`, `containers`, `mtl`;...

A (useful, I think) partial fix would be to use hackage's package description editing feature and put an upper bound (

Oops, I believe we got #653 and #658 mixed up in the last 3 comments!

A lot going on here. I'll attempt a summary. * the goal is to speed up `fromList` (borrowing ideas from `fromAscList`, which builds the whole map in a bottom-up fashion...
