I don't think it would be all that horrible.  Nor is it
completely wrong.  I've done:

	open( X, "y" ) || die "Couldn't open Y.";

lots of times even though:

	open( X, "y" ) || die $!;

prints much better error messages.  Sometimes it's because
of the large number of OPEN statements I'm using.  I've
also found that always putting the filename is double
quotes helps prevent "Not Found" statements.
