One import, e.g. use foo::bar or use foo::bar as baz. Also produced for each element of a list use, e.g.

Glob

Glob import, e.g. use foo::*.

ListStem

Degenerate list import, e.g. use foo::{a, b} produces an additional use foo::{} for performing checks such as unstable feature gating. May be removed in the future.
