If we were to create a Rust version of this page for Haskell, what cool programming techniques would you add to it?

What madness caused this

[–] SorteKanin@feddit.dk 22 points 1 month ago (1 children)

It's a test for the compiler which ensures that these legal yet extremely weird expressions continue to compile as the compiler is updated. So there is a purpose to the madness but it does still look pretty funny.

That’s make sense. We used to write some ridiculous tests too, but users still managed to find a way


fn union() {
    union union<'union> { union: &'union union<'union>, }
}

Is my favorite.
