Using a hash containing arrays, I want to print out a list sorted over all array elements while maintaining the hash entry name.

To illustrate, I borrowed an example from perldoc/perldsc on Hashes of Arrays

In the last part of the example I can print out the list by creating a temporary list of all the names in the arrays, then sort and print it. However, at that point I no longer have the "family name" hash entry association. So, I then re-iterate through the hash and arrays to match the sorted members list with their original hash entries and print from there.

What I want is something like this:

 astro:jetsons,
 barney:flinstones,
 bart:simpsons,
 elroy:jetsons,
 fred:flintstone,
 ...

BTW: normally sorting by hash key (and then possibly within an array) is what I want, so I "think" I have the correct data structure. However, sometimes I will want to sort over all items in all arrays.

The code below works but I just can't help to think that there's an easier or better way to do it.
Any help finding the better way is appreciated.

Thanks

#!/usr/bin/perl -w

use strict;
use Data::Dumper;

my %HoA = ( 
        simpsons    => [ "homer", "marge", "bart" ], 
        flintstones => [ "fred", "barney" ], 
        jetsons     => [ "george", "jane", "elroy", "astro" ], 
); 
#
# This is the type of sorting normally needed.
#
print "Sorted by number of members then name\n";
foreach my $family (sort {@{$HoA{$b}} <=> @{$HoA{$a}} || $a cmp $b } k
+eys %HoA){ 
    print " $family: \t", join(", ", sort @{ $HoA{$family} }), "\n"; 
} 
#
# Sometimes this sort will be needed.
#
my @members;
# Dump all names into a single array
foreach my $family (keys %HoA ) {
    push (@members, @{$HoA{$family}} );
} 
#Sort it and find it's family association for printing
foreach my $name (sort @members) {
    foreach my $family (keys %HoA) {
        foreach my $test (@{$HoA{$family}}) {
            print " $name : $family\n" if ($test eq $name);
        }
    }
}
