#### 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!
}
```
