bro is code golfing, it's a cool kata to codegolf, he's good

Forked and approved

I tried to run your solution without {-# LANGUAGE ImportQualifiedPost #-} and tests passed. You also need to change import Data.Traversable qualified as T to import qualified Data.Traversable as T

Already rejected

Try to add {-# LANGUAGE Haskell2010 #-} and fix compilation errors. It seems the issue is because of lib used to validate imports. It fails if code is not a valid Haskell2010.

Навзаєм. Якщо ти питаєш про ()(), то це IIFE

Вітаю. Розкажи будь-ласка, що тут відбувається?

Drunk? my boy is as high as the clouds hahaha

Exactly, what I said. :D

I don't think that's an issue. It's more work than the expected solution, so considering the probable rank of the kata, it's fine.

I don't see how that should prevent the kata from approving. It's not like this results in an exploit of a high level kata. I wouldn't worry too much about such solutions on an easy kata.

what's wrong with solution ... it's the same difficulty solving it this or that way
