Hello, I was repeating the properties of some basic type classes yesterday and ended up reading through the "Overview" section in 'Data.Traversable'. I was deeply impressed and wondered why I hadn't noticed it before, and so I realized, it is there since base-4.15.0.0. I wanted to deeply thank whoever took the time to write this up. In my opinion, we need more of this in the Haddocks, and on Hackage. Thank you! Dominik PS: I also noticed that when reading Haddocks of the 'base-4.15.0.0' package on Hackage, the link 'Contents' on the top right does not link to the usual overview about the package including all package versions, but only to the contents of the documentation of the current version. I liked the general overview about package versions more.
