Lua stack basically works as an arena if you aren’t eager to clean it. I guess in C one could macro hack himself a similar arena to borrow objects from python runtime. In C++ it’s a matter of befriending a smart pointer with ref/unref calls. It was probably done hundreds of times in all sorts of python embedding wrappers.
