+Two items of the same name cannot be imported without rebinding one of the
+items under a new local name.
+
+Erroneous code example:
+
+```compile_fail,E0252
+use foo::baz;
+use bar::baz; // error, do `use bar::baz as quux` instead
+
+fn main() {}
+
+mod foo {
+    pub struct baz;
+}
+
+mod bar {
+    pub mod baz {}
+}
+```
+
+You can use aliases in order to fix this error. Example:
+
+```
+use foo::baz as foo_baz;
+use bar::baz; // ok!
+
+fn main() {}
+
+mod foo {
+    pub struct baz;
+}
+
+mod bar {
+    pub mod baz {}
+}
+```
+
+Or you can reference the item with its parent:
+
+```
+use bar::baz;
+
+fn main() {
+    let x = foo::baz; // ok!
+}
+
+mod foo {
+    pub struct baz;
+}
+
+mod bar {
+    pub mod baz {}
+}
+```
