   1 The `self` keyword cannot appear alone as the last segment in a `use`
   2 declaration.

   4 Erroneous code example:
   5
   6 ```compile_fail,E0429
   7 use std::fmt::self; // error: `self` imports are only allowed within a { } list
   8 ```
   9
  10 To use a namespace itself in addition to some of its members, `self` may appear
  11 as part of a brace-enclosed list of imports:
  12
  13 ```
  14 use std::fmt::{self, Debug};
  15 ```
  16
  17 If you only want to import the namespace, do so directly:
  18
  19 ```
  20 use std::fmt;
  21 ```
