Lua template

Using Lua 5.2 but I believe it applies for all the other versions

Missing optional nil return values on next()

local tab = {}---@type {[integer]: {[string]: string}}
local index, value = next(tab)
print(index) -- This line should warn for need check nil
print(value.first) -- This line should warn for need check nil

string.match returns string? (not string|number)

return city_name:match(".*, .*, (.*)") --- Incorrect type warning here

latest Vscode, latest master

string.match returns string? (not string|number)

string.match can return integer with local startPos, finishPos = string.match('()somewords()')

I'm considering change it to return any, and supports analysising parameters to determin return types in the future

I did not realize this.
