The language just promotes that it's easy to parse so that tools can be written to automatically transform source code in certain ways. Eclipse has a lot more refactorings than just reorder method arguments. Lua should theoretically fall into the same bucket of languages, it's just that there probably are fewer tools for refactoring so far. Compare that to languages like C++ where despite its age and being used to widely there are still very few working refactoring tools. (All that being said, I usually used method argument reordering when removing or adding arguments to a method by changing what the method is doing and then noticing that a different order makes more sense when reading.)
