assert(loadstring(something))()  ?    Like that, except that the "something" should come from a socket, and Lua should enter "assert(loadstring(something))()-mode" whenever it's idle - maybe even wh

Uh, so the Lua interpreter assigning a module to a global variable is okay but for require() it's not okay? No, global variables are indeed very evil. We regularly have problems with them in the Nmap

loadfile() returns a function whose body is the file's contents. So to load a config file which is Lua code, you'd do something like: local cfg = assert(loadfile('config.lua')) config = cfg() assumin

Good point, I don't have this problem because I mainly use trusted data (I just use sandboxing sometimes to cacth some function results). However you can have trusted data (and run it with Lua) and

I think this issue is overblown. But one way to address it is to redirect all global lookups through an emphemeron table indexed by the coroutine itself. This works well for situations where you just
