Thanks. But there seems to be still something wrong...:

/tmp/haskell117106-5-1qthoyp.q2vhzadcxr/Main.hs:6:32:
    Not in scope: `isPrime_55'

/tmp/haskell117106-5-1qthoyp.q2vhzadcxr/Main.hs:6:50:
    Not in scope: `isPrime_55'

/tmp/haskell117106-5-1qthoyp.q2vhzadcxr/Main.hs:6:70:
    Not in scope: `isPrime_55'

Is Haskell translation still buggy? I got this when either running sample tests or attemping:

/tmp/haskell117104-5-qnrxd6.yzsnvobt9/undefined.hs:1:8:
    Could not find module `Codewars.IsTwinPrime'
    Use -v to see a list of the files searched for.```
