Comment (by vdelecroix):
Replying to [comment:2 jdemeyer]:
> Is there a reason why the hash ''should'' be the same as the one for the
polynomial?
No idea. But it make sense. It was the previous implementation. I did not
want to break anything.
On the other hand, it does not take the parent into account and 'sqrt(2) +
3/2' and 'sqrt(3) + 3/2' would have the same hash.
What do you think?
