yes, there are lots of trouple with it...for example, I don't think it
is good to base it on the container type when basing it on an iterator type
would be
more flexible.

perhaps, but so much interested in the actual a user
I just wished the functionality was there to use...just like I don't
have to code an indirect iterator, but can use boost::indirect_iterator.

If there is agreement that the two iterators would be a good idea, I
don't mind adding a proper implementation.
