Re: [FUN] Codegolf: Lua 5.3-only program

[Spar <developspartv@...>]

Already late.
assert(_VERSION:find("5.3"))
28 characters. (Unescaped dot is intentional,  someone suggested :match(3), didn't test it might work at Lua 3.x)

assert(#("1"+1 .."")>1)
23 characters.

dofile("1"+"2")

provided you do have a file named "3.0" but no file named "3"

Follows the same idea as
assert(#("1"+"2".."r")>2)

but that's too long ;-)
