# =============================================================================
# 到 — Creates an inclusive range with a Latin keyword.
# =============================================================================
#
# What this teaches:
#   • Inclusive range — `范围 <initium> 到 <finis>` iterates including both endpoints
#   • Range iteration — combining `遍历` with `到` for bounded loops
#
# Common mistakes:
#   • confusing 到 (inclusive range bound) with 当 (loop) or 区间 (range type)
#
# See also: 迄, …
# =============================================================================




# 到 — inclusive upper bound for range iteration
#
# 遍历 范围 <initium> 到 <finis> <var> { … }   -- both endpoints included
#
# GRAMMAR:
#   iterStmt :← '遍历' '范围' expr '到' expr binding block
#
# EXPECTED OUTPUT:
#   0, 1, 2, 3 (inclusive range through finis).

main {
    # i = 0, 1, 2, 3 (includes 3)
    for range 0 until 3 const i {
        print i
    }
}

Expected output:

0
1
2
3
