Re: Stop the deprecation of Data.Monoid.{First,Last}

A deprecation would need a viable migration path. I don't have one, and I don't want to invest more time into this right now. I think we should refrain from anticipating a future deprecation since that seems to cause library authors not to provide instances for these types: https://www.reddit.com/r/haskell/comments/g3glwn/migration_path_for_last_c/f...

or ... are we merely slowing down the deprecation path? are there technical reasons aside from paucity of effort for eventual removal?

it might be good to add some remark that the semigroup version is *more* strict/the moniod version is *less* strict?

Thanks for the feedback, everyone! :)

Since option (C) received the most support, I opened an MR to implement it:

https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3154

Once it is merged, I will make an announcement of this change, as requested on r/haskell:
