In Lua 4.1 you can "compile" the code without running it, with
loadstring/ loadfile. Moreover, you can build a secure environment
changing the global table to a new one, that does not contain dangerous
functions (such as writeto and execute). As an extreme case, you can
use an empty global table, if all you want is to rebuild some data
structure.
