Probably right.

I have nothing against that it we can figure out a simple algorithm for
returning (for example) US English when the caller asks for any English.
How would we do that with these strings -- would this do it:
(find (lambda (available-language)
(string-prefix? user-langauge available-language))
available-languages)
Would probably have to do something so that asking for "e" doesn't
return "en".
