Can we add a pretty printing type class similar to the Pretty class in ansi-wl-pprint? Then we wouldn't need separate packages like prettyclass and pretty-class. A class provided by pretty itself would also get wider adoption.


It looks like pretty-class is already marked as deprecated, so authors should be migrating to prettyclass instead. Adding a new one for pretty could make the problem worse.

Agreed. I've emailed Lennart to see if he is interested in merging prettyclass as-is into pretty and then deprecating that package. If he is on-board then I think that makes sense. Otherwise I agree adding a third option isn't good.

Spoke with Lennart and he is supportive of deprecating prettyclass and merging it into pretty, so doing just that.
