1t Note: $#array is not the length, but the biggest index.

2nd note:use strict 

#!/usr/bin/env perl
use strict;

my $ar1 = [1,2,3];
my $ar2 = [4,5,6,7];

my @arrays = ($ar1,$ar2);

foreach my $ary (@arrays) {
    print $#{ary}, "\n";
}

3d note: Read perldata and perlref! Really, that helps a lot!

4th note: 

#!/usr/bin/env perl
use strict;
use warnings;

my $ar1 = [1,2,3];
my $ar2 = [4,5,6,7];

my @arrays = ($ar1,$ar2);

foreach my $ary (@arrays) {
    # correct syntax
    print $#{@$ary}, "\n";
    # correct length
    print scalar(@$ary), "\n";
}
