As someone who's used Lua a lot as an embedded language in the VFX industry (The Games industry wasn't the only one that used it for that!), and had to deal with wrapping C++ and Python APIs with Lua (and vice-versa at times!), this is indeed very annoying, especially when tracing through callstacks to work out what's going on.
Eventually you end up in a place where it's beneficial to have converter functions that show up in the call stack frames so that you can keep track of whether the index is in the right "coordinate index system" (for lack of a better term) for the right language.
Oh that’s super interesting, where in the VFX industry is Lua common? I typically deal with Python and maybe Tcl (I do mostly Nuke and pipeline integrations), and I can’t think of a tool that is scripted in Lua. But I’ve never worked with Vega or Shake or what this is/was called
Katana uses LuaJIT quite extensively for user-side OpScripts, and previously both DNeg and MPC (they've largely moved on to newer tech now) had quite a lot of Lua code...
Oh, I had no idea! I don’t have much to do with Katana, I just assumed it was also all python
