Build failed with ghc version 8.10.1 This was due to a change that took place in ghc 8.8.1 (release note).

I quickly fixed it so that everything builds again. Though I am not an expert so please be careful with this.

Thanks, it's good but I like to also keep compatibility with older base versions. Do you agree with https://github.com/leftaroundabout/constrained-categories/tree/compatibility/monadfail ?

Everything works fine for me with the monadfail branch. Thank you !
