Marks a test hook as applying to every case.

# =============================================================================
# omnia — Marks a test hook as applying to every case.
# =============================================================================
#
# What this teaches:
#   • Exhaustive matching — `discerne omnia` requires every variant of a `discretio` to have a `casu` branch.
#   • Safety guarantee — The compiler rejects incomplete matches, eliminating forgotten variant bugs.
#
# Common mistakes:
#   • Using ceterum with discerne omnia — omnia forbids catchall arms; list every variant explicitly.
#
# See also: praepara, postpara
# =============================================================================

# omnia — exhaustive discerne (must cover every variant)
#
# discerne omnia <discretio> { casu <Variant> { … } … }
#
# GRAMMAR:
#   matchStmt :← 'discerne' 'omnia' 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 casu
    match all condicio {
        case Activa { return "activa" }
        case Quietus { return "quietus" }
    }
}

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

Expected output:

activa
