2020-11-18 01:34:09 <koz_> You can also avoid the need for Arbitrary if you just define 'Gen a' for your stuff, and use combinators like https://hackage.haskell.org/package/QuickCheck-2.14.2/docs/Test-QuickCheck.html#v:forAll
2020-11-18 01:34:22 <koz_> Or rather, define stuff like 'genFoo :: Gen Foo' and use those.
2020-11-18 01:34:45 <koz_> It's more tedious though.
