The documentation shows an example of OOP, but it's very small and don't
cover all aspects of OOP.

Needing C++ runtime is an issue to me.

By API I mean the C functions you call to initialize the language (like
lua_open), call functions etc.

I need just one language.

My customers will be the ones doing OOP to extend the application in
whatever language I present to them. They won't program in C++.
