The variant of an enumeration has the same name as the function implemented for it, but this does not conflict and cannot call this function

[A4-Tacks]

The variant of an enumeration has the same name as the function implemented for it, but this does not conflict and cannot call this function

Example

fn main() {
    let _x = Foo::Value(0, ());
    //let _y = Foo::Value(0); // error
}
pub enum Foo {
    Value(usize, ()),
    Nil
}
impl Foo {
    /// It cannot be used, and no errors!!
    #[allow(non_snake_case)]
    pub fn Value(num: usize) -> Self {
        Self::Value(num, ())
    }
}

Info

• cargo check no errors and warnings.
• rustc --version: rustc 1.70.0 (90c541806 2023-05-31)
• rustc +nightly --version: rustc 1.72.0-nightly (fe7454bf4 2023-06-19)

Expected

error[E0592]: duplicate definitions with name 'Value' or this function can be called

This is similar to #76347 which reports the same problem with associated constants.
