So you did some limited testing now and it worked. That's a good thing,
but it doesn't guarantee that it will work in all cases now and in the
future. As a general principle, we should try to move Sage as close to
Python 3 as possible. Python 3 has only new-style classes, so we should
use new-style classes.

easier the porting will be.
True, but besides the point.
And of course, this just means that we should use new-style classes
everywhere in Sage.
