[Question / Feature Request] Disable global variable

I have a problem when concerning the lpeg library. The re module has a conditional if that defines re globally if and only if the version is Lua 5.1. However since it is global, the automated add require path won't trigger (e.g. on version 5.3). My first idea was to disable the global variable. This doesn't seem possible. Any suggestions?

首先在 Lua 5.1 和 5.3 下复现 lpeg re 模块的行为，重点关注其条件性全局定义和自动 require 路径。然后检查 language server 如何处理 globals 和 require 建议。完成的标准是：确定并记录禁用全局 re 变量的预期行为，同时处理 Lua 5.1 兼容性和 Lua 5.3 的 require 检测。
