Note that there would be an ambiguity with PEP 3132, though. We (and Pyrex)
did pretty well without unary* for quite a while. I'd be very careful with
adding it now. Especially for something like iterators, i.e. a concept that
Python already has (even if it looks and works different in the two
languages), and for which dereferencing is a totally unrelated concept from
a Python POV.
