Commentary in examples
Hi. I saw your edits to the Lua example for Hello world/Text. You noted "RC is not a Lua tutorial". I'd like to disagree; while Rosetta Code is not literally a tutorial, it is most certainly a resource for introducing people to programming languages they are unfamiliar with. I think the best examples are those which include commentary on their use of their language's features.
I considered reverting your edit, but I did not do so since you claim that the text was also incorrect, and I do not recall enough Lua to know how to correct it. If you could add a correct description, I would appreciate it (but you are by no means obligated to do so).
(Disclaimers: (1) This comment is partly motivated by defense of examples-with-commentary I have myself written; I prefer they not become unwelcome on RC. (2) I happen to be an administrator, but I do not set RC policy; this is strictly my opinion as a contributor.)

- Hi Kevin, thanks for being nice while I was a bit blunt.
- Regarding commentary not becoming unwelcome on RC, I was just showing my lack of experience here by my comment. However, I felt the commentary as it was was out of place in the Hello world example, where most languages just have some subtle variation on print("Goodbye World").
- That it "works with Lua 5.1.1" is unremarkable, as it would have worked since the first release (v1.1, 1994).
- Having two separate versions, one with parens and one without, and a comment, just seems unnecessary. Since omitting the parens is a syntactic sugar which a minority of languages have, I'd prefer the "without" version, but per your comment I'll revert deleting that particular comment (but with corrections).
