That's exactly Maybe.withDefault "something", which is a great example of
partial application.

Ah, that makes sense. Take the value out of the Maybe box.

That is what I meant. I will often use this pattern as follows:
orSomething : Maybe String -> String
orSomething str =
case str of
Just str -> str
Nothing -> "something"
I realize, though, that I misunderstood the original question.

David, are you sure you didn't mean the following?
case something of
Jus
I think the problem is slightly different than you think. The reason the
compiler complains about the redundant pattern is that "x" already matches
everything. There are no more cases for "_" to handle.
This compiles with no problem:
let
x = 1
in
case something of
x -> ...
Thanks for clearing things out!
