But Smartmatch is smart enough to match on numeric equality: 
>perl -wMstrict -le
"for my $ar (
   [1, 1, 0, 1],  [0],  [0, 0, 0],
   [qw(0)],  [qw(00)],  [qw(000)],  [qw(1 1 0 1)],
   [1],  [],  [1, 10, 01, 101, 010],
   [qw(1 10 01 101 010)],
   ) {
   print qq{(@$ar): }, @$ar ~~ 0 ? 'naught' : 'not'
   }
"
(1 1 0 1): naught
(0): naught
(0 0 0): naught
(0): naught
(00): naught
(000): naught
(1 1 0 1): naught
(1): not
(): not
(1 10 1 101 8): not
(1 10 01 101 010): not

Update: Added 'numeric string' test cases.
