Suggest changing _x to x instead of a use of x to _x #60164
Closed
Description
Variables can be marked as unused by prepending with an underscore. If at some point such a variable is used again, the compiler suggests to name the use _x, even though every single time I have encountered this, what I wanted is to change the definition of _x to x.
fn main() {
let _x = 42;
let y = x;
