Ok, I don't see an obvious way using the flip-flop operator....Please enlighten us...

This idea using reduce which essentially has the equivalent of a foreach index did occur to me: 

use strict;
use warnings;
use List::Util qw(reduce);

my @arr = qw(0 3 5 12 3 2 1);;
my $maxi = reduce { $arr[$a] > $arr[$b] ? $a : $b } (0..@arr-1);  
print "maximum i = $maxi  value=$arr[$maxi]\n";
# maximum i = 3  value=12

Oh, and yes I almost always use @array-1 instead of $#array because I tend to either forget the right characters or type it somehow wrong.
