ok, I'm gonna skip over the WHY part of the question....
thank Japhy for his clear signs of dementia - and note
for folks at home that in

http://www.wetware.com/drieux/pbl/perlTrick/HashGames.txt

we point out one of the few times when that unDerefed trick
is really worth having around...

I figured it would be simpler to do something like

   sub WhoofMe {
     my ($msg, $key, %hash ) = @_;
     print "$msg\n";
     for my $ref (@{$hash{$key}}){
         my $gotone=ref($hash{$ref});
         print "$ref refs $gotone $hash{$ref}\n";
     }
   } # end of WhoofMe

to gin up the data to verify Japhy's Psychosis with:

        Different Copies:
        A1 refs ARRAY ARRAY(0x126fc)
        A2 refs ARRAY ARRAY(0x128b8)
        A3 refs ARRAY ARRAY(0x12918)

        Same by Hash Slicing:
        A1 refs ARRAY ARRAY(0x12978)
        A2 refs ARRAY ARRAY(0x12978)
        A3 refs ARRAY ARRAY(0x12978)

so that if the FRUITLOOP brigade really wants to play the
rest of this gambit out and change the A1 stuff and then note
that say

        print "$ref refs $gotone $hash{$ref} :-> @$hash{$ref}\n";

then they would have a framework to play that skank...
        
ciao
