Description
fn main() {
match Some(vec![3]) {
Some(vec![x]) => (),
_ => (),
}
}
Gives error message:
error: unexpected `(` after qualified path
--> src/main.rs:3:14
|
3 | Some(vec![x]) => (),
| ^^^^^^^
| |
| unexpected `(` after qualified path
| in this macro invocation
|
= note: this warning originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)
But this is clearly wrong as there is no (
in the span pointed to.
