Starts the default branch of an elige or discerne statement.

# =============================================================================
# ceterum — Starts the default branch of an elige or discerne statement.
# =============================================================================
#
# What this teaches:
#   • Default arm — `ceterum <block>` is the catch-all branch in an `elige`
#     or `discerne` match expression
#   • Fallback handling — when no `casu` pattern matches, execution falls
#     through to the `ceterum` block
#
# Common mistakes:
#   • using `ceterum` with `discerne omnia` — `omnia` forbids catchall arms and requires listing every variant explicitly (SEM044)
#
# See also: elige, discerne
# =============================================================================

# ceterum — default elige arm
#
# GRAMMAR:
#   defaultClause :← 'ceterum' block
#
# EXPECTED OUTPUT:
#   Scalar stdout smoke (see body).
#
# BACKEND:
#   Cross-ref: elige/ceterum.fab.

main {
    const _ tag ← "z"
    switch tag {
        case "a" { print "a" }
        default { print "default" }
    }
}

Expected output:

default
