"Given a list whose elements are strings (containing only letters, as they are actually English-language words), how would one print that list only on the condition that at least one of the strings in the list contains no repeated letters?" 

#!/usr/bin/perl

# http://perlmonks.org/?node_id=1202179

use strict;
use warnings;

my $good = [qw( allo mallo malo)];
my $bad  = [qw( tillo sillo sallo)];

grep !/(.).*\1/, @$_ and print "@$_\n" for $good, $bad;
