`extern use foo` has the some of the same drawbacks as `use crate foo`. The `use` might lead people to think you can do `use crate foo::bar`. The fact that there wasn't a whole lot of love for any particular options suggests maybe we should wait for more ideas.
It occurs to me now that `extern foo` would probably work too. jack.
