Using Net::LDAP, I'm running into a problem trying to deal with multiple instances of an attribute. It appears that they get stored in a hash as an array of arrays; in the initial hash ($valref), I can dump the values like this: 

@pktClassList = @$valref{packetclassifierlist};
print "class = ";
foreach my $i (@pktClassList) {
  foreach my $j (@$i) {
    print "$j\n";
  }
}

Unfortunately I need to get @pktClassList to another sub as a member of a different hash. I'm assigning it to the hash in a switch statement like this: 

...
case /packetclassifierlist/    { $tlvHash{pktClassList} = "@pktClassLi
+st" }
...

I then pass $tlvHash to my new sub as "newSub($tlv,%tlvHash);". In newSub I'm doing this: 

...
my ($tlv, %tlvHash) = @_;
...
my $classArray = $tlvHash{pktClassList};

foreach my $i (@$classArray) {
  print "i = $i\n";
  foreach my $j (@$i) {
    print "j = $j\n";
  }
}

I've tried various permutations of @, $, and @$ around classArray and tlvHash, but if the code executes at all, the best I get is "Can't use string ("ARRAY(0xa3f6e4)") as an ARRAY ref while "strict refs" in use...." I'm really trying to stick with packing this into %tlvHash instead of passing it as a separate arg, because multiple functions are calling newSub and they won't all have this attribute.
