// Here we test that the parser is able to recover in a situation like
// `for ( $pat in $expr )` since that is familiar syntax in other languages.
// Instead we suggest that the user writes `for $pat in $expr`.
#![deny(unused)] // Make sure we don't trigger `unused_parens`.
fn main() {
let vec = vec![1, 2, 3];
for ( elem in vec ) {
//~^ ERROR expected one of `)`, `,`, `@`, or `|`, found keyword `in`
//~| ERROR unexpected parentheses surrounding `for` loop head
const RECOVERY_WITNESS: () = 0; //~ ERROR mismatched types
}
