It does, kindof (there's other ways to import the functions after you've
done "use" without doing so, but I'm not going to go into them).  One
way of importing just that funciton to your namespace is:

 use Net::SNMP qw(&oid_lex_sort);

Look for EXPORTS in the pod for the module and you'll see what else you
could have imported.  That function could also be imported by:

 use Net::SNMP qw(:snmp);

or, of course:

 use Net::SNMP qw(:ALL);
