PS: at the risk of not getting precise answers for my more technical
questions, I would like to hear your opinions about the need of
metaprogramming in lua. As scheme, lua provides powerful basic
mechanisms that lend themselves to implement new control structures,
programming paradigms, etc. This often implies boilerplate code that
cannot always be abstracted out into reusable functions (maybe because
the function calling syntax isn't ideal for the specific construct,
maybe because the function calling semantics is inadequate).
