Debug.crash is used when you know a condition is impossible. I have a library where I sort a non empty list and do case analysis on the result. I call Debug.crash on the empty list case. It can't happen because sorting doesn't change the length of the list, but building that into the type system is way to complicated for Elm's goals.
Language and tooling features are focusing on "making impossible things possible" not "making possible things pleasant", so Debug.todo is unlikely to get implemented anytime soon. But I think it's a pretty neat idea! -- You received this message because you are subscribed to the Google Groups "Elm Discuss" group.
