An alternate approach is just to use 'never' from elm-community/basics-extra directly for your '[WHAT HERE?]'. Although the error case actually comes first, so your example should be
Task.perform [WHAT HERE?] NewEntry Time.now and my preferred answer would be (assuming 'import Basics.Extra exposing (never)') Task.perform never NewEntry Time.now It ends up being exactly the same thing under the hood - I just prefer this version because I find it very explicit, it's a little bit shorter, and most importantly it builds a nice solution out of little generic, modular pieces instead of using a more specialized function (if you can get used to how 'never' is used here, then you might be able to find uses for it elsewhere).
