Side question for all of you who are saying “the Lua language is very stable”: do you mean you're staying on Lua 5.1/5.2? If so, is this driven by LuaJIT essentially freezing everything in place by grabbing so many users and libraries off the PUC-Rio implementation? If not, what counts as stable to you? Lua 5.3 and 5.4 both have dialect incompatibilities with prior versions.
I consider Lua 5.1/5.3/5.4 to be roughly their own language. Somewhat akin to a Python2 vs Python3. Completely manageable transition if you want, but best to stick to an implementation if you can. Within a platform, there are seemingly only ever bug fixes.
For anyone who doesn't want to follow the link, the practical gist in that case is indeed that LuaJIT wins and they don't care about later Luas. (Edited somewhat for wording post facto.)
