…rochenkov Avoid prematurely choosing a glob import Fixes rust-lang#153842 Use the following without introducing trait to explain: ```rust mod a { pub use crate::x::y as x; // single import #1 } mod b { pub mod x { pub mod y {} } } use a::x; // single import #2 use b::*; // glob import #3 fn main() {} ``` In current implementation, when `#1` is first resolved, `crate::x` is temporarily taken from glob import `#3` as `crate::b::x`. This happens because `single_import_can_define_name` will see that `#2` cannot define `x` (because it depends on `#1` and `#1` is ignored) and then return `false`. Later, during finalization, `crate::x` in `#1` resolves through single import `#2` instead, which no longer matches the initially cached module `crate::b::x` and triggers the ICE. I think the resolver should keep this unresolved because `#2` may still define `x` to avoid prematurely choosing a glob import. r? petrochenkov
