Using `Self::EnumVariant` fails

[varkor]

enum Enum {
    Variant,
}

impl Enum {
    fn choose() -> Self {
        Self::Variant //~ ERROR no variant named `Variant` found for type `Enum` in the current scope
    }
}

I'm not sure if this is supposed to be allowed or not, but the error message is incorrect. Is there an up-to-date document describing all the places Self is allowed instead of a type name?

This is #49683

Thanks, I tried searching but managed to overlook this!
