The official documentation isn't 100% clear on things (why am I getting LUA_TNIL for functions?), and the best I can find with some simple web search is kinda relevant stackoverflow (🤮) posts, except they're mostly about calling host functions from Lua side, the rest are things that seem I've nailed so far.

EDIT: Solution was that everyone was using luaL_dofile, while I was forward thinking and used lua_load instead, which isn't a macro, and as such doesn't do an initial lua_pcall. Now I do it manually, and now I get different, but less cryptic and actually documented errors. Now I just have to wrestle with D metaprogramming features (very strong and capable, but is a rabbit hole itself).

Not really sure what you're trying to achieve here. Do you have an application that lets you use Lua extensions? Or do you want to build an application that lets you use Lua extensions?
