+The `self` import appears more than once in the list.
+
+Erroneous code example:
+
+```compile_fail,E0430
+use something::{self, self}; // error: `self` import can only appear once in
+                             //        the list
+```
+
+Please verify you didn't misspell the import name or remove the duplicated
+`self` import. Example:
+
+```
+# mod something {}
+# fn main() {
+use something::{self}; // ok!
+# }
+```
