Is there any reason for set slardar as a global variable in init phase ?

[fankeke]

hello
As I see, in init phase, slardar has been declarded as a global variable,

But global variable has side effect in ngx_lua, so why doing this ,any sepecial consideratin for this?

slardar could be declarded as a module level variable that could achieve the same goal .

--init.lua

local slardar = require "config"

slarder.kk= "any operation you want"

--foo.lua
local slarder = require "config" --has been cached by package.loader
--you can use slader.kk here

thanks .
