Varargs worst case

["Soni \"They/Them\" L." <fakedme@...>]

A long time ago I created what I believe to be the worst case for 
varargs handling:

https://github.com/SoniEx2/Stuff/tree/master/lua/Forth

(Note that the code is not particularly good but it does do the "varargs 
hammering" pretty well IMO)

I'd consider this a good benchmark for varargs performance across versions.

I'm pretty sure if this code worked in Lua 5.0 the performance would be 
worse than bad, but luckily it doesn't work!
