I'm using the Net::SNMP module to requests for gets and walks to a server, I thought it would be a good idea to use the lex_oid_sort function to get my array of OIDs in to a logical order before sending the requests. The strange thing is, the function always returns an array where the first element is "Net::SNMP" with the rest of it being the sorted OIDs. Here's a test I threw together: 
use strict;
use Net::SNMP;
my @unsort = qw/ 1.3.6.1.2.1.1.5 1.3.6.1.2.1.1.4 1.3.6.1.2.1.1.1 1.3.6
+.1.2.1.1.2/;
my @sort = Net::SNMP->oid_lex_sort(@unsort);
local $, = "\n";
print @unsort;
print "\n-------\n";
print @sort;

Output:

Any clue why it's doing this? I'm fairly new to this whole perl module thing, but the documentation doesn't say anything about this kind of behavior.
