Actually I jumped in mostly to show off the elegance of

use in select("language")

Which will close the alias or do nothing if it wasn't open, thus skipping the "if used(..." check. When I saw that for the first time and understood what it does (and how), believe me, I had a smile on my face. (of course you believe me - had I said I had the smile somebody else's face, or elbow, that would be harder to believe...)
