Introduces a branch inside an เลือก or แยก statement.

# =============================================================================
# กรณี — Introduces a branch inside an เลือก or แยก statement.
# =============================================================================
#
# What this teaches:
#   • Pattern matching arms — `กรณี <expression> <block>` defines a branch in
#     an `เลือก` match expression
#   • Default fallback — `อื่น` provides the catch-all branch when no
#     `กรณี` pattern matches
#
# Common mistakes:
#   • non-exhaustive match without a `อื่น` catchall — every `เลือก` or `แยก` must cover all possibilities or add a `อื่น` arm
#
# See also: เลือก, แยก
# =============================================================================

# กรณี — branch arm in เลือก or แยก
#
# GRAMMAR:
#   casuClause :← 'กรณี' expr block
#
# EXPECTED OUTPUT:
#   Scalar stdout smoke (see body).
#
# BACKEND:
#   Cross-ref: เลือก/elige.fab, แยก/discerne.fab.

main {
    const _ code ← 200
    switch code {
        case 200 {
            print "ok"
        }
        default {
            print "other"
        }
    }
}

Expected output:

ok
