Required modules' returns' types are wrong when more than a single value is returned

[artemking4]

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows WSL

What is the issue affecting?

Type Checking, Diagnostics/Syntax Checking, Libraries

Expected Behaviour

First type should be a number, second - a string, third - a boolean

Actual Behaviour

Reproduction steps

main.lua

local number, string, boolean = require "required"

required.lua

return 1337, "string", true

Additional Notes

No response

Log File

No response

[sumneko]

File can only return one value, I will add a diagnostic about it.

[artemking4]

ehh, well, in some environments it can return more than one, can we have a switch or something for that?

[sumneko]

This is a non-standard behavior.
There are countless non-standard behaviors in the world, and I don't want to add switches to them one by one.

[artemking4]

well, this library already supports non-standard environments, like love2d and special operators like /*, //, && and ||, so why not add this? Personally, i would expect this to be a feature even in the vanilla lua, not sure if it actually supports that though.
Is it something that is hard to implement maybe?

This is why I added https://github.com/sumneko/lua-language-server/wiki/Plugins .
Besides, /* ,// are famous non-standard symbols, like I built in some famous environment definition files such as love2d, skynet.
