【高级技巧】Lua尾调用：裁决之杖仓库千层整理的栈复用

local function stackUp(actor, depth)
    if depth == 0 then return "ok" end
    return 1 + stackUp(actor, depth - 1)  -- 加法破坏尾位，栈逐层涨
end

local function sortCells(actor, depth, acc)
    if depth == 0 then
        sendmsg(actor, 1, "裁决之杖仓库整理完成 " .. acc .. " 毫秒")
        return "ok"
    end
    return sortCells(actor, depth - 1, acc)  -- 尾调用，栈帧复用
end
