Well, for what it's worth, my vote goes for a multi-argument \case. I find the
comment on the wiki page about mistyping "\case Just x" instead of "\case (Just
x)" a lot a bit disingenuous, since you already need these parens with today's
lambda.
But you don't need parentheses with today's case. I.e. you write
\x -> case v of
Just x -> y
Nothing -> z
then you would also expect to be able to write
\case
Just x -> y
Nothing -> z
And \case looks more like case than like lambda, particularly because it uses
layout.
As for single argument \case, I don't really see the need for it, but I am not
against. So I'll abstain from voting.
