Marks a test hook as applying to every case.

# =============================================================================
# 全部 — Marks a test hook as applying to every case.

#
# What this teaches:
#   • Exhaustive matching — `匹配 全部` requires every variant of a `判别` to have a `情况` branch.
#   • Safety guarantee — The compiler rejects incomplete matches, eliminating forgotten variant bugs.
#
# Common mistakes:
#   • Using 默认 with 匹配 全部 — 全部 forbids catchall arms; list every variant explicitly.
#
# See also: 备置, 收尾
# =============================================================================

# 全部 — exhaustive 匹配 (must cover every variant)
#
# 匹配 全部 <判别> { 情况 <Variant> { … } … }
#
# GRAMMAR:
#   matchStmt :← '匹配' '全部' expr '{' casuClause* '}'
#
# EXPECTED OUTPUT:
#   none — stdout not pinned for this exemplum.

union Condicio {
    Activa,
    Quietus
}

fn narra(Condicio condicio) → string {
    # every variant must have a 情况
    match all condicio {
        case Activa {
            return "activa"
        }
        case Quietus {
            return "quietus"
        }
    }
}

main {
    const Condicio condicio ← variant Activa
    print narra(condicio)
}

Expected output:

activa
