cause we like the perl-ish way better :) But i think the point is that in perl, the array (assuming that's the context) indices themselves aren't needed. For example,

for (my $i = 0; $i < $#array + 1; ++$i){
  print $array[$i] . "\n";
}

Is "better" written:

foreach my $s ( @array ){
  print "$s\n";
}
# OR one of many other ways like:
print $_."\n" for @array;
[download]

Of course, if the output needs the array index in it, that changes things...
