Hi Christian,
Please try again now (after a cabal update). I uploaded List-0.4.4 which removes mapMaybe, and then also uploaded List-0.5.0 which re-adds it. hexpat should now be using List-0.4.4 as it wants List < 0.5
I'll follow up with a few steps: * Make myself a rule to test installing hexpat before I push updates to List in future. * Contact Stephen to change hexpat to not use unqualified open imports, at least for List.
His email was not in the package description. Christian
* Add docs to my package warning users that using it with unqualified open imports may be more dangerous than usual (btw unqualified open imports are always dangerous) because List exports functions which generalize Prelude functions and shares their names by design. Similar to how Control.Category exports "." and "id".
Cheers & Happy coding, Yair
