Oh, no, I don't want it. :)  I just was killing time reading py-ideas while eating lunch and was somewhat surprised by the ability to return a tuple as the context manager result and have it unpack appropriately, nothing more.  I absolutely would never use my example code a production environment, and if not there, then why even bother using it in a hacked up one-time script, where I'd just leave the files open and assume they'll be closed on exit...
