> WoW [...] have no interest in dealing with the slow reference VM
Does WoW use LuaJIT? I thought it used the reference Lua 5.1 VM, simply because that was the newest version when it was first released.
> Plans to further support to new versions for luajit are...well they exist.
I’m not sure it’ll ever happen. AFAICT LuaJIT is so complex that only its author, Mike Pall, understands it well enough to make major changes. He has expressed his dislike for several of the changes in Lua >= 5.2.

I didn’t mean to imply WoW was using luajit, apologies. I was under the impression that over the years they have patched and fussed with code of the reference VM to resolve some performance pain points in the vanilla UI lua. Unfortunately, I can’t find the source for that.
Regardless, I’ve always assumed that they had little interest in both rewriting their vanilla UI to newer versions AND starting over from square one trying to resolve any performance hiccups they hit.
