For Haskell solution you can either probably
import Prelude hiding (minimum, maximum)
after the module line or just remove the
(minimum, maximum)
from the module line.

Haskell Stderr in running of tests gives a warning. Probably a change in the compiler or something.

Haskell sample tests try to import Example module when the code has Banjo. Resulting in

ExampleSpec.hs:6:8:
    Could not find module `Example'
    Use -v to see a list of the files searched for.

You can just change import Example to import Banjo in tests as a workaround, but not everybody might realize this.
