  Okay, another bad example.  That's what I get for trying to bring a
proper filter command into things.  Say instead "baz" was a lame
post-processor which only accepted a single input file.  Then the
following should work, yes?

	baz <( cat <(foo Fred) <(foo Wilma) <(foo Pebbles) )

  (That is somewhat contrived, but I've encountered endless lame
software before, with endless ways to be lame, so it's not completely
implausible.)

  So keep going!  I'm trying to encourage the sharing of information, here.  :)
