# =============================================================================
# ปิดล้อม — Declares or explains an inline closure expression; compact ∴
# syntax is preferred for new code.
# =============================================================================
#
# What this teaches:
#   • Closure basics — `∴` (therefore) introduces a closure body after the
#     parameter list
#   • Compact syntax — the `∴` form is preferred over block-delimited closures
#     for simple expressions
#
# Common mistakes:
#   • confusing `∴` (ปิดล้อม joint for compact closures) with `ดังนั้น` (single-statement body joint for `ถ้า`, `ขณะ`, `กรณี`) — they are not interchangeable
#
# See also: ∴, ฟังก์ชัน, ทำ, จับ, ให้
# =============================================================================

# ปิดล้อม — closure bodies with ∴ and ⇥
#
# GRAMMAR:
#   closureExpr :← paramList '∴' expr
#
# EXPECTED OUTPUT:
#   Scalar stdout smoke (see body).
#
# BACKEND:
#   Cross-ref: clausa/clausa.fab.

main {
    const (int) → int dupla ← int x ∴ x * 2
    print dupla(5)
    const (int, int) → int ผลรวม ← (int a, int b) → int ∴ a + b
    print ผลรวม(2, 3)
}

Expected output:
