--- Comment #14 from Jonathan Wakely <redi at gcc dot gnu.org> --- I think I'll just change the formal argument name to locale instead of args. We only want to accept a single argument, not a list, and now $locale works because it's not a list. I should audit the other procs in libstdc++.exp to see if the same change makes sense.
