I've done it once for a project but abandoned it during a major rewrite
of the application. The problem was that I was having to consult the
documentation (err..., the source code) much more that I used to consult
the Lua docs. I ended up with just a couple of functions, one being to
lua_pcall and get a nice stacktrace if things go wrong for example.
Your example is exactly like what I was trying to do, and every time I
had to call State.getTable I wondered what the default argument values
were and if the method would cause any side effects besides calling
lua_gettable.
So from my experience, stick to the Lua API if you're already familiar
with it, and write a couple of functions on top of the API to make your
life easier.
Cheers,
Andre
