1. Implement Functor[Try]. Check that your implementation passes the property check, just like it did in this chapter.
2. Implement Applicative[Try]. Check that your implementation passes the property check, just like it did in this chapter.
3. Implement Applicative[Either]. Check that your implementation passes the property check, just like it did in this chapter.
4. Implement Traversable[Try].
5. Implement Traversable[Either].
6. Implement Traversable.compose, in the same way, that we discussed at the end of this chapter.
