The bonus for this issue currently seems to be impossible to do reliably, as the compiler seems to lack span information for item names alone, like `Foo` in `struct Foo { ... }`. It would be possible to hack something together by computing span offsets, but that seems like a solution that would be begging for trouble.

A proper solution to this would, of course, be to add span information to the right place (seems to be `rustc::hir::Item::name` but I may be wrong).
