	Is there a way to force a subroutine to return a null array?
Or. rather, I would like to do this:

	open( FILE, $file );
	@array = do subrtn( $stuff, $n, $nonsense );
	while ( $#array >= 0 ) {
		# fiddle $stuff and $nonsense
		# ...
	} continue {
		@array = do subrtn( $stuff, $n, $nonsense );
	}
	close( FILE );

I would be grateful if someone would present a way to do this, for the way
I'm trying to work things may be tripping a bug in my copy of perl, and I'm a
bit beyond my frustration point at the moment to try tracking down whether
it's a bug in perl or an error in my understanding of its behavior.  [Most
likely the latter, but after about four hours one begins to wonder....]

	Thanks ever so much.
