+#### Note: this error code is no longer emitted by the compiler.
+
+The `pub` keyword was used inside a public enum.
+
+Erroneous code example:
+
+```compile_fail
+pub enum Foo {
+    pub Bar, // error: unnecessary `pub` visibility
+}
+```
+
+Since the enum is already public, adding `pub` on one its elements is
+unnecessary. Example:
+
+```compile_fail
+enum Foo {
+    pub Bar, // not ok!
+}
+```
+
+This is the correct syntax:
+
+```
+pub enum Foo {
+    Bar, // ok!
+}
+```
