`unpack` is only present in 5.2 of it's compiled with 5.1 compatibility enabled (i.e. LUA_COMPAT_UNPACK or LUA_COMPAT_ALL were defined).
If you're writing solely for 5.2, use `table.unpack`. If you're writing for 5.1 and 5.2, you can use `local unpack = unpack or table.unpack` at the top of the file and then call it as `unpack`.
