I have never seen so many cheating solutions in Kata.

otherwise omniBool = undefined.
thx natan for your reply.

I don't think that this kata translates particularly well to Haskell, but that doesn't look broken to me. It's up to you to make that "work". See the sample tests for what you're asked to do.

Need to fix import lists (haskell ver.)

test/FinalSpec.hs:12:22: error:
• Variable not in scope: (==) :: Bool -> Bool -> t0
• Perhaps you want to add ‘==’ to the import list in the import of
‘Prelude’ (test/FinalSpec.hs:3:1-36).

This is a bad task for level 6. Look at the comments. Only participants with 1,2 kyu and 1,2 dan are satisfied.

My solution makes me happy

expected: Just "f(x) = x + -1"
but got: Just "f(x) = x - 1"

make my day

Hint #1 is very good.

bruteforce is possible too

thank you

Incredible. My solution is better than the rest in the first time.
