There are certainly plenty of examples in other languages (For example [1].  I've already got WGS84 to NZTM in Lua, but that's of limited interest to the rest of the world).  So it's not a big deal to translate to Lua.   Since it's a very standard kind of thing, I figured I'd ask to try to keep the number of implementations down.
