Unless I'm completely wrong (as is my wont today for some reason) -- the
lua_State which things outside of the VM know exists, is what is known as an
"opaque type" in that we know a lua_State is a struct, and we always deal in
pointers to it.
Without the actual layout, it's unlikely that you could inherit from it.
Also I'm not completely convinced that C++ allows you to inherit a class
from a struct, although I could be wrong there too.
