Why I get the error " PolyvariadicFunctionsSpec.hs:1:53:
Not in scope: main' Perhaps you meant min' (imported from Prelude) " even after resetting ?

'alr approved some time ago'

'alr approved some time ago'

I think you can use a simple array here, which saves a call to malloc

Thank you B1ts.
Test suite did not run on GHC 8.2, the final test did though.
Problem solved.

This happens with GHC 7 IIRC. Is GHC 8 available?

Hi,

After a lot of study I pass all tests. I now know who is superhero "Lambda man" !

Submitting Haskell solution gives error:

OddsAndEvensSpec.hs:1:53:
    Not in scope: `main'
    Perhaps you meant `min' (imported from Prelude)

Can somebody update the kata please?

Well, the ones that have been updated might not work with the old version, so on most, it will probably be disabled.

so it means in every haskell kata we can still select either versions, right? thanks for explaining :)

Its because some katas haven't been updated yet, so the version hasn't been removed yet. It will be removed eventually.

oh, okay. but it makes me wonder why we have the GHC 7 option listed though...

Make sure you have GHC 8.2 selected.

can compile using the test button, but when clicked "Attempt", following message showed up:

Kata/AdditionCommutesSpec.hs:12:8:
    Could not find module `Test.Hspec.Codewars'
    Perhaps you meant
      Test.Hspec.Compat
      Test.Hspec.Core (from hspec-2.2.4@hspec_GEAgkH1Gbr9BY0qzvd784f)
      Test.Hspec.Core.Tree
