Good luck and have fun dealing with your bosses in Bangalore.

Yes, as you saw from my email this was more or less my suggestion and I
had already tried it.

The trouble is that for some reason it causes SNMP walks to no longer
work. An object ID is created, its number-list is taken, then it is modified.

I guess there is no hope but to actually fix the problem and delve even
further into ASN.1.

I was hoping that you might already have a plan to start using simple
vectors of integers as OIDs. Using lists/instances is more
complicated and wasteful.

PS. Why do you hate loop and iterate so much?
