Triage, the error message has improved slightly, but no change (I updated the example code & diagnostics). It's worth noting that import paths are actually different to normal paths, since e.g.
foo::<T>::bar::<U>is a validpath, but not a valid import path.(For completeness, I believe there's no import paths that are invalid normal paths, e.g.
super::super::foo()is a valid expression.)steveklabnik commentedon Apr 30, 2015
