// Let's make it possible to create pure functions even when we're 
// dealing with impure operations that would have side effects!

Generic Elm types exercises

A series of exercises to get a feel for how generic types and type variables work in Elm. For each of these, you are given some code that is not compiling. Your task is to get it compiling. You can change the body of the function but not the signature. No cheating with Debug.todo or infinite recursions either 😉
