Declares an inferred immutable local.

# =============================================================================
# đặt — Declares an inferred immutable local.
# =============================================================================
#
# What this teaches:
#   • Immutable binding sugar — `đặt name` is a compact alternative to
#     `hằng _ name` for inferred-type immutable locals
#   • Supports immediate init (`đặt x ← expr`) and deferred init
#     (`đặt x` then `x ← expr` later)
#
# Common mistakes:
#   • Confusing `đặt` (sugar for `hằng _`) with `biến` — `đặt` creates an immutable binding.
#
# See also: hằng, biến, ←
# =============================================================================



# đặt — inferred immutable bindings
#
# Immediate init:
#   đặt tên ← expr        -- compact sugar for hằng _ tên ← expr
#
# Deferred init:
#   đặt tên               -- compact sugar for hằng _ tên (assign once later)
#   tên ← expr
#
# Prefer đặt when a block chains several inferred locals; keep hằng _ when
# teaching the explicit infer marker or mixing typed and inferred bindings.
#
# GRAMMAR:
#   sitDecl := 'đặt' IDENTIFIER ('←' expression)?
#
# EXPECTED OUTPUT:
#   sit.expected

main {
    let salve ← "Salve"
    let tên ← "Marcus"
    let nuntius ← "§, §!"(salve, tên)

    print nuntius

    let label
    label ← "deferred"
    print label

    const _ idem ← nuntius
    print idem
}

Expected output:

Salve, Marcus!
deferred
Salve, Marcus!
