In my update to LuaBridge, I added support for three styles of
"Lifetime Management" which directly address the use-cases you
described:

- Lua lifetime: Managed completely by Lua
- C++ lifetime: Managed completely by C++
- Shared lifetime: Reference counted with your choice of compatible container.

These lifetime models are fully documented in the LuaBridge README:

Specifically:

https://github.com/vinniefalco/LuaBridge#c-lifetime
https://github.com/vinniefalco/LuaBridge#lua-lifetime
https://github.com/vinniefalco/LuaBridge#shared-lifetime

The LuaBridge Demo graphical application (which works on most
platforms) has example code for creating objects using all the various
lifetime models, using the provided reference counted containers:

If you have questions feel free to contact me or open an Issue on Github.

Thanks
