Wildcard imports from `super` omit non-public constants and statics.

[koute]

Please consider the following code:

const CONSTANT: usize = 0;

mod ok {
    use super::CONSTANT;
    fn foobar() -> usize {
        CONSTANT
    }
}

mod error {
    use super::*;
    fn foobar() -> usize {
        CONSTANT
    }
}

The ok::foobar compiles fine while error::foobar generates the following error:

error[E0425]: unresolved name `CONSTANT`
  --> test.rs:13:9
   |
13 |         CONSTANT
   |         ^^^^^^^^ unresolved name

This also affects static.

Marking the constant pub makes it compile as expected.

Actually, sorry, it seems that this isn't specific to constants; a wildcard doesn't import anything non-public.

Is this intended? I'd expect a * to expand to everything that is importable from a given scope, not only what is public.

The code will compile if you add #![feature(item_like_imports)] to the crate root.

After #37127 lands, item_like_imports will become a default and the code will work without any features.

@petrochenkov I see; thanks!

Sorry for the duplicate bug! I did try to search for duplicates, but it seems that my search-fu wasn't strong enough.

@koute: you can still close it. 🙂
