I think you misunderstood my second paragraph. What I’m saying is that in order to do anything complex in it, you’ll have to reimplement important parts that are lacking, using all these meta/parametric things in your “mylualib”, and all this mud will drown you when you’re most vulnerable.
Toying with it with all the free time on one’s hands is okay.
Avoiding useful techniques is an option, but doing it when the world of saner alternatives exists feels like self-sabotaging.
Hmm, that makes a little more sense than what I thought you were saying. I still don't think it's correct, though. Lua has those facilities already; you don't have to implement them yourself. My point is that it isn't like programming in assembly or C where you either implement them yourself or do without. When OO or reflection is the saner alternative, in Lua, you can just use it.
I see your point and have even shared it, but my experience with real-business Lua was miserable and actively laughed at. Which was, I must admit now, absolutely deserved.
