This syntax is no longer accepted:

15:23 < [Coke]> rakudo: enum foo <>; say foo[1]
15:23 <+p6eval> rakudo ce15be: OUTPUT«===SORRY!===␤Unsupported use of 
<>; in
                Perl 6 please use lines() to read input, ('') to 
represent a
                null string or () to represent an empty list at line 1, 
near
                "<>; say fo"␤»


Can you rewrite the code to show the problem or show it's closable? 
Thanks.
