Replying to [comment:12 jdemeyer]:
> If finite fields will now embed by default in the algebraic closure, the
hashes should be preserved.
I am not sure that this really is a good idea:
https://wiki.sagemath.org/EqualityCoercion
In the long run we might have to move away from our "mathematical"
implementation of `==` but this is not the focus of this ticket.
The changes propose here are a clear improvement of the current situation
and seem perfectly fine to me.
