Well the truth of the matter is that there are quite a few trees. The 
bad news is that iterators are way more subtle than one might think. The 
good news is that most of the time you won't realize that. Though that 
might cause problems down the line. Think about the old don't derive 
from an iterator problem. You can get away with it for a long time.

As far as the library doc's are concerned I think they have to deal with 
the trees, though it is perfectly possible that the docs are to focused 
on the subtleties.
