Urr? How often do you dup filehandles as opposed to reading filehandles?
I think we would be much better off with
$thingy = $STDIN;
reading a line from $STDIN rather than duping it. Otherwise, we'll be
constantly having to type five more characters (.next) for a very common
practice.
I'm also concerned about the confusion between C<$MARK.next> and C<next
$MARK> (of course, we haven't seen whether C<next> is going to change).
At the very least, wouldn't C<$STDIN.read> be better and more orthagonal
with C<read(STDIN)>.
