I was wondering if Ops could help me out, I didn't have enough time to
test it though before I posted my question.

For what I am doing, it looks like this may be the easiest solution.
I need to make sometime and test this in my project.

Now that is interesting. At first, I was playing around with
System.Object and then decided to use int. It just seems that runtime
might be slower if I used objects and I would possible need GetTypes()
at some point. I don't know at this point, just thinking out loud
here. But maybe your custom MyDict example may be best. I need some
time to think this thru.

Greatly appreciated!
