That doesn't really answer my question.

Where do you store the stack with regard to the iterator?
Iterators need to be copyable, so you can't just store it in the
iterator itself.

So you use an intrusive_ptr to deal with this (which is not thread-safe,
by the way).
This could cause some problems with comparison.

Your operator== seems incorrect, it compares the values, and does very
weird things with null values.
