For Haskell:

  1. I'd say this is definitely a wtf. Tuples should have never been given Foldable instances and I'd immediately reject any code that uses it in code review.

  2. I actually didn't know, so TIL. Not surprising since common wisdom is that a lot of the type class instances for Doubles are pretty weird/don't make a lot of sense. Just like in any language, floating point needs special care.

  3. This is jjust expected syntax and not really a wtf at all. It's very common for languages to require whitespace around operators.

  4. Agreed as wtf, the NegativeLiterals should be on by default. Just would be a pretty significant breaking change, unfortunately

  5. Not a wtf... What would you expect to happen? That operation is not well-defined in any language
