I don't think so. They're interchangeable at that level.

Yes - I was doing something complicated like that and hit on the
tokens thing as a way to simplify and speed things up. I'll probably
have to go back that way again. BTW - the item count thing won't work
because you still don't know the order, especially in cases where
there are multiple quotes and/or possible comment chars.
