There was a problem hiding this comment.
I think we can use it in a second function, which actually sparked your initial comment about adding a short-circuiting fold_left: std.contract.any_of. The Ok/Error cases are reversed though, so you might have to dualize each step and the final result with e.g.
let flip = match {
'Ok x => 'Error x,
'Error x => 'Ok x,
}
As far as I'm concerned, I like the name.

| value |
