 * ── Scope ──────────────────────────────────────────────────────────────────────────────────────
 *
 * A `<group each="Depts">` puts its element in scope for every line inside it, nested groups
 * included, so `${{Depts.name}}` and `if="Doctors.dept.id == Depts.id"` are names there. The scope
 * is carried down as a list: what the enclosing groups publish, plus what the line itself walks.
