Well, I was talking about vanilla Lua. Anyway, the above difference is very weird because it doesn't allow to postpone the usage of varargs, for instance, in some coroutine create/resume loop where arguments could be anything generic. Fortunately, I rely on this behavior only within a testing framework which is run under plain Lua.
