 Did you not see where I said I didn't try it with Lua 5.3? I took the
time to create code [1] that had a large number of locals and I got the
following:
Lua 5.1:
nil [string "local x1 = 1..."]:201: main function has more than 200 local variables
Lua 5.2:
nil [string "local x1 = 1..."]:201: too many local variables (limit is 200) in main function near '='
LuaJIT 2.0.3
nil [string "local x1 = 1..."]:201: main function has more than 200 local variables
 And just to be pedantic:
Lua 5.3.0-work2:
nil [string "local x1 = 1..."]:201: too many local variables (limit is 200) in main function near '='
 I know the limit is 200.

 I know that, and I never argued against using locals. I just expressed
concern that importing a large number of modules might impact local usage. 
And while 200 locals might be considered "large enough" for normal usage,
not everybody is going to do normal things.

 And you did. So there is that.
