我目前正在制作一个系统，因为我需要识别太多的东西为nil或{}，我正在寻找这样的方式:
本地lorem ipsum,悲哀,坐下 = {}, {}, {}, {}
我会这么做，但是我能在1个地方识别多少个单词呢?
Lua有一个硬编码限制，可以在Lua源文件的lparser.c中找到:
/* maximum number of local variables per function (must be smaller
than 250, due to the bytecode format) */
#define MAXVARS 200
也就是说，无论使用了多少个local声明，任何函数最多只能声明200个局部变量。
这听起来和看起来都像是一个X/Y问题，所以我的主要问题是为什么
您最多可以使用200个变量，因为根据经验测试，Lua只允许您在任何代码段中使用200个局部变量。
(注意，从这里的注释判断，似乎限制实际上应该是256个局部变量。这是在Windows的Lua上测试的。显然，你的里程可能会有所警惕。)
是的，你可以声明并给他们一个值只用一个local声明。

输出从1到200的所有数字。
添加1个变量，至少windows的Lua会给出这个错误:
