+Attempt was made to import an unimportable value. This can happen when trying
+to import a method from a trait.
+
+Erroneous code example:
+
+```compile_fail,E0253
+mod foo {
+    pub trait MyTrait {
+        fn do_something();
+    }
+}
+
+use foo::MyTrait::do_something;
+// error: `do_something` is not directly importable
+
+fn main() {}
+```
+
+It's invalid to directly import methods belonging to a trait or concrete type.
