> Even though it doesn't even get that much slower at a certain number of rows it just starts hanging Yes, this brings back memories. I've definitely seen this kind of behaviour as well, in many different, not-particularly-exotic, situations. I am absolutely convinced the issue I raised on the github project was a bug or a defect, despite the maintainers not taking it seriously. I find QuickCheck and Clojure spec/test.check much more straightforward to use. I just never ran into this sort of thing with these other tools.
