That makes sense.  I don't think it'd quite work in this case, because I
want to open several files all at once, do a ton of work that populates
them with files, and then close them all.

This is a nice idiom, though.  In C, I've been sort of missing that idiom,
which I first encountered in Ruby.  (I mean, spelled differently, but the
same basic thing.)
