I want to use an array for the keys of a hash, and I want that array to point at another array as the values in the hash, something like the following: 

my @multiKey1 = ("a","b");
my @stuff1 = ("1", "2", "3");

my @multiKey2 = ("c","d");
my @stuff2 = ("4", "5");

my @multiKey3 = ("e","f");
my @stuff3 = ("6", "7");

my %testHash = ( \@multiKey1 => \@stuff1, \@multiKey2 => \@stuff2, \@m
+ultiKey3 => \@stuff3);

The problem right now is, although I can get access to the arrays again if I access a specific value with a specific key, I can't get access when I just try keys() to start out. E.g. 
@testHashKeys = keys %testHash;
@testHashValues = values %testHash;
$tmp = @testHashKeys;
foreach (@testHashKeys){
        print "deref bla = @$_ = $_\n";
}
foreach (@testHashValues){
        print "deref bla = @$_ = $_\n";
}
$ref = $testHash{$testHashKeys[0]};
@valueArray = @$ref;
print "valueArray = @valueArray\n";

For this, I get the following output, and I don't understand why :-/ 
deref bla =  = ARRAY(0x10082add0)
deref bla =  = ARRAY(0x10082afc8)
deref bla =  = ARRAY(0x10082aed8)
deref bla = 1 2 3 = ARRAY(0x10082ae48)
deref bla = 6 7 = ARRAY(0x10082b040)
deref bla = 4 5 = ARRAY(0x10082af50)
valueArray = 1 2 3

The key thing is the line: print "deref bla = @$_ = $_\n"; If it knows that $_ is an array reference, why doesn't @$_ dereference it to give me the array values printed out, like everywhere says it should, and like happens with the values array? I greatly appreciate you taking the time to read this :)
