Oops. I wrote that email on my latop - it was a file never checked
into source code control. Looking back it was a plan for allowing
us to use named tuples on older versions of Python. Sorry!

But I have come up with another easy task instead,

(7) Update exception style from this,

except ErrorClass, variable_name:

to this:

except ErrorClass as variable_name:

The second form is the only allowed syntax in Python 3,
but was not possible under Python 2.5.
