Sorry, poor quoting on my part. I was attempting to reply to Andreas's earlier points:

I see no point in Functor or Foldable for tuples.

        I believe he was referring to lists, not to tuples. There were  few Prelude functions limited to tuples before FTP, and those haven't changed.

    I didn't say that. I was referring to his response to my post, that
    "Some delusions have very sophisticated explanations."

    This is entirely subjective, and frankly I don't think that post-FTP
    Haskell is a "mess" or is "unpleasant to use". If anything, it became
    more useful to me, because now Prelude functions aren't limited to the
    one data structure I almost never use.
