Since this erm… discussion has also brought in Haskell and in this case, the name, the history etc are related I thought I'd mention the following
Around 2015 there was a major upheaval in the Haskell community around the socalled FTP (foldable-traversable-prelude) controversy. In many respects this controversy is analogous and even identical to this one and the heat there was considerably more than this thread's storm-in-a-teaspoon Mark Lentczner resigned as Haskell's release manager¹ which in the python world would be analogous to say Raymond Hettinger saying “Python 3 is too much of a mess; I am going to stick to python 2.2” Along with hims went other stalwarts like Lennart Augustsson and Eric Meijer's widely acclaimed EdX course switched from haskell to hugs² [which is like switching to python 1.6] The controversy somewhat oversimplified is that foldr (reduce-from-right) was foldr : (a → b → b) → b → [a] → b It was changed to foldr : Foldable 𝒯 ⇒ (a → b → b) → b → 𝒯 a → b If we think of [a] as list_of_a and 𝒯 a as any general list-like interface we would see the close parallel with the divergence of opinion on this thread ¹ http://haskell.1045720.n5.nabble.com/quot-Excuse-me-I-think-this-i-my-stop-quot-Resigning-from-the-Platform-td5819861.html ² https://www.reddit.com/r/haskell/comments/3ove2e/got_the_welcome_email_from_edx_fp101x_course_hugs/ -- https://mail.python.org/mailman/listinfo/python-list
