Hello:
I've followed the lua OO tutorials and have kind of gotten it working. My issues seem to come in when trying to translate this to c, however. I'm not sure why it's such a hard problem for me. I'm mainly looking for examples of how to do this in c-side API, as there are tons of lua OO ideas floating around out there.

 HTH,
