Confusing diagnostic when `use Self::Variant` inside an impl

[fee1-dead]

I tried this (play):

pub enum Uwu {
    Hi
}

impl Uwu {
    fn a() -> Uwu {
        use Self::Hi;
        Hi
    }
}

Heres the current output:

   Compiling playground v0.0.1 (/playground)
error[E0432]: unresolved import `Self`
 --> src/lib.rs:8:13
  |
8 |         use Self::Hi;
  |             ^^^^ `Self` is only available in impls, traits, and type definitions

For more information about this error, try `rustc --explain E0432`.
error: could not compile `playground` due to previous error

The label that says "Self is only available in impls" is misleading since it is already in an impl.
