The changes seem to have been copied to the kata manually, so rejecting.

When you have only 1 function, the use of the pipe macro is not recommended.

We've added Elixir 1.6.4. See our blog for more info.

Agreed. Test case is f = x * x with n = 4 over [2,6]. I don't see how this can be -6.0.

Seems test cases are expecting wrong results!

Translated to Elixir.

Fixed, thanks :)

The description promises us "k will always be >=1."

The haskell random tests

    it "passes random test" $ property $
      ((\x y -> josephus x y == josephus' x y 0) :: String -> Int -> Bool)

generate negative and zero numbers as well. Above should be

    it "passes random test" $ property $
      ((\x (Positive y) -> josephus x y == josephus' x y 0) :: String -> Positive Int -> Bool)

Approved, thanks :)

Added Elixir implementation!

Thanks. I forked it and made the update there, since I couldn't just update it and save.

Inverter.invert(numtest, list) has an extraneous argument in the sample tests.

+1 random test broken.
