Dear all, I've been increasingly relying on data-default-class, but sadly it doesn't look like it's currently maintained; there are some tickets on the github issue tracker that would need some attention. I have tried contacting the authro/current maintainer Lukas Mai (CC'd) by email but have not received an answer so far (I hope he's doing well, btw). This is my first public request for taking over the `data-default` family of packages: data-default-class data-default-instances-base data-default-instances-containers data-default-instances-dlist data-default-instances-old-locale data-default Kind regards, Marco Zocca (http://hackage.haskell.org/user/ocramz)
