Unexpected name conflict between a method and a function

[Y-Nak]

What is wrong?

When a method name is identical to another function that is defined outside of the struct, the compiler emits an invalid name conflict error.

pub fn ident(x: i32) -> i32 {
    return x
}


struct MyS {
    pub fn ident(self, x: i32) -> i32{
        return x
    }
}

error: function name `ident` conflicts with previously defined function
