Hi,

There is no tests in Compose.hs. I am looking for some examples on how to create instances of the Compose type and how to test the functions requested in the exercises.

Thanks,

Alex

Hello Alexander,

The Compose exercise is about finding which will be unachievable. Of those that are achievable, one of those has only one possible answer and the other one can usually be arrived at either by following the types alone, or with a little guidance. Give it a crack.

Hi,

Thanks for the reply! I came up with solutions and they typechecked (in all "possible" excercies). Unfortunately without the tests the only way for me to verify that I was correct was to go to the repository with the answers. I was. On to the Traversable.hs!
