Yeah, Lua metaprogramming facilities are very powerfull, you can use it as a
simple imperative language, but you can turn it out into a functional or
object oriented language, you can implement inheritance, multiple
inheritance, delegation, messaging, etc. There are also many different ways
of binding code to lua. There are binding generators (tolua, swig), but
another posibility is to take advantage of reflexivity. If you already have
a reflexive class system, it should be possible to bind it to lua. See for
example the bindings to com and corba. I haven't too much experience with
other language bindings, but I've heard that lua c interface is very low
level, and that it's easier to write bindings for other languages
(javascript, io). The result of that is that lua may be simple on the
surface, you can use it as a simple language, but you can also use it in
more complex ways. However, taking the correct decisions and doing it right
for the first time may not be that easy.
