Thanks. I never got involved in Python development before, so I will
take a look at the development process. I took a quick look at the
affected C files and must confess that I need more time looking at them
to learn everything around it. However, I think that the behaviour of
file handling should change so that any class derived from file should
support the >> operator 'properly' (ie the derived class write() method
should be called).
