Are you aware of the existence of the Lua programming language, and the word "lua" meaning "moon" in Portuguese?
If such confusion would be often, we will change the name, however, we've got few comments that this name could be confusing but in fact nobody ever confused it.
We are still open to change it and are actively looking for any kind of replacement. If you have any idea of a name that would be suitable for such a language, I would be more than interested in hearing it.
Moreover, I just opened a thread on our forum to discuss names propositions. If you've got any ideas, please share them with us! :)
So I'd be one of those who'd suggest a re-branding, because the Levenstein distance is not big enough and there is too much potential for brand pollution on both fronts. Lua got to the moon first - you should shoot for another distant body, imho.
