Excellent news! How did you test it? One way would be to make it callable by C and then use testu01 but perhaps you have already done this or similar? See here for a bit more detail: https://idontgetoutmuch.wordpress.com/2017/01/14/calling-haskell-from-c/ <https://idontgetoutmuch.wordpress.com/2017/01/14/calling-haskell-from-c/>. Testing the split function might need thinking about though.
