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

+Example of erroneous code:

+```compile_fail
+use std::fmt::self; // error: `self` imports are only allowed within a { } list

+
+To use a namespace itself in addition to some of its members, `self` may appear

+use std::fmt::{self, Debug};

 The `self` import appears more than once in the list. Erroneous code example:
