Assuming =:
=iterator # the iterator itself, passable (autoreffing)
$=iterator # get one element
@=iterator # get remaining elements, lazily
This would mean we'd get
for @=$fh -> $line { ... }
or
=it := =$fh; # =it := $fh.it # =it = $fh.it # I dunno.
for @=it -> $line { ... }
Ugly.
Another alternative would be
$fh.it # the iterator itself, passable
=$fh # synonym for $fh.it.next, where a real iterator has .it
# returning $self, so that =$iterator and =$handle both
# work, without special magic.
