+error[E0277]: the size for values of type `str` cannot be known at compilation time
+  --> $DIR/issue-14366.rs:2:14

+LL |     let _x = "test" as &dyn (::std::any::Any);
+   |              ^^^^^^ doesn't have a size known at compile-time
+   |
+   = help: the trait `Sized` is not implemented for `str`
+   = note: required for the cast from `str` to the object type `dyn Any`
+help: consider borrowing the value, since `&str` can be coerced into `dyn Any`
