It's interesting seeing someone else's choices.  pipes seems very
nice, but puts everything in temporary files, which is not what I
wanted.  It also has the $IN $OUT magic names which is easier for
badly behaved commands than assuming a command reads from stdin and
writes to stdout.

I want to ask my initial question again, which was badly phrased.  You
have a generator, and a program that needs a file handle.  Can you
adapt the generator to the file handle without consuming the whole
thing?
