Yes, none are show stoppers. Lua suits perfectly for for the use it was designed: small embeddable scripting. I hope no one is writing millions of lines of lua code! For me even small amount just does not "feel right" the way for example ruby does. That's why I've been eagerly waiting for mruby but unfortunately it does not (yet) fill the void.
