Invalid suggestion to use a vertical bar in let a, b = x; #61573
Description
Introduced in #57008, the following program
fn main() {
let a, b = x;
}
yields the following message:
error: unexpected `,` in pattern
--> src/main.rs:2:10
|
2 | let a, b = x;
| ^
help: try adding parentheses to match on a tuple..
|
2 | let (a, b) = x;
| ^^^^^^
help: ..or a vertical bar to match on multiple alternatives
|
2 | let a | b = x;
| ^^^^^
However, the suggestion let a | b = x; is nonsensical.

let a | bis supposed to work eventually (#48215, #54883), but it's not yet implemented.goffrie commentedon Jun 7, 2019
I see. However, in this case,
a | bwould still not be a legal pattern.compiler-errors commentedon Aug 13, 2022
This was resolved.
