Nicu,
What you are askiing to be able to do seems (to me) to be rather perverse.
When you construct the polynomial ring you are specifically specifying
that its variable be the string 'x', but later you want to change its name
(as you do know how to do thanks to the other replies). 'x' is just a
string. I tried changing the __repr__ method of 'x', but python will not
allow that.
