I'm currently making a system, since I need to identify too many things as nil or {}, I'm looking for a way like this:
local lorem, ipsum, dolor, sit = {}, {}, {}, {}
I will do it, but how many words I can identify in 1 local?
This sounds and looks like an X/Y question so my main question back would be why, but I'll bite.
You can do at most 200 variables, because by empirical testing, Lua only allows you to have 200 local variables to any piece of code.
(Note that judging by a comment here, it may seem that the limit is actually supposed to be 256 local variables. This was tested on Lua for Windows. Your mileage may wary apparently.)
And yes, you can declare and give them all a value using just 1 local declaration.

Outputs all the numbers from 1 through 200.
Add 1 variable to this, and at least Lua for windows gives this error:
C:\Program Files (x86)\Lua\5.1\lua.exe: test.lua:1: main function has more than 200 local variables
