Comment:

On lines 316 and 317 of sage/rings/polynomial/polynomial_ring.py, you write 

except (NotImplementedError, ValueError): 
    raise TypeError, "denominator must be a unit"

I don't think a NotImplementedError should lead to a TypeError: that would give a lot of confusion.

Otherwise, this all looks very good.

(this ticket now depends on #7644)
