Description
I'm seeing an internal compiler error on the following input (found by fuzz-rustc):
struct S {} impl S { fn foo(&mur Self) {} } fn main() {}
$ rustc main.rs
error: expected identifier, found keyword `Self`
--> main.rs:3:17
|
3 | fn foo(&mur Self) {}
| ^^^^ expected identifier, found keyword
error: expected one of `:`, `@`, or `|`, found keyword `Self`
--> main.rs:3:17
|
3 | fn foo(&mur Self) {}
| -----^^^^
| | |
| | expected one of `:`, `@`, or `|`
| help: declare the type after the parameter binding: `<identifier>: <type>`
