+// This tests the parser recovery in `recover_intersection_pat`
+// and serves as a regression test for the diagnostics issue #65400.
+//
+// The general idea is that for `$pat_lhs @ $pat_rhs` where
+// `$pat_lhs` is not generated by `ref? mut? $ident` we want
+// to suggest either switching the order or note that intersection
+// patterns are not allowed.
