Re: Haskell Foldable Wats

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

...

Use of tuples is highly discourageable… I see no point in Functor or Foldable for tuples.

It's a bit bold to simultaneously say "Nobody should use this type," and also "If you use this type, you should do it this way." If you think that it's bad practice to use tuples, that's a fine and respectable opinion, but at that point you should start being a bit more wary about telling those who think otherwise /how/ they should use them.

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.
