Yes, that's what Luiz suggested. But it's not exactly efficient (think
of embedded systems) unless a wrapping loading function is used on the C
side, as he said. Both techniques are not exactly elegant, especially in
a clean language like Lua.
Besides, it could be convenient to be able to execute a chunk in
different environments without reloading it.
(I'm not complaining, I'm just trying to fully understand the motivations)
