If you are looking for stringification of an array, try
$hash{0} = "@array";
If you are interested in the length of the array, try
printf "array = %s\n", scalar @array;
Also run and study this:
#!/usr/bin/perl
use strict;
use warnings;
my $array = [6, 7, 8, 9];
my %hash;
$hash{0} = $array;
print "array = @{$array}\n";
print "hash = ", @{$hash{0}}, "\n";
print "hash = @{$hash{0}}\n";
__END__
after reading perlref.
