Adding new public items is not a breaking change?

[tesuji]

This section adding new public items states that

adding new public items is currently a breaking change, due to glob imports

But look at this example (playground):

mod baz{
    use foo::*;
    mod foo {
        pub fn bar() {
            println!("bar");
        }
    }

    pub fn bar() {
        println!("foo");
    }
}

use baz::bar;

fn main() {
    bar()
}

It compiles fine with the output:

foo

It's no longer a breaking change for the "glob vs non-glob" situations, but the breakage is still possible for "glob vs glob" conflicts.

mod m1 { pub fn f() {} }
mod m2 { pub fn f() {} }

use {m1::*, m2::*};

fn main() {
    f();
}

Thanks for the info. Should we add this case to the rfc?
