Comment(by cremona):
I have only just started to look at this -- not a review as yet!
Question: why the "lift" methods for number field elements? It appears
to do exactly the same as polynomial():
{{{
sage: x = polygen(QQ)
sage: K.<a> = NumberField(x^3-2)
sage: b = K.random_element(); b
1/16*a^2 + 3*a + 1
sage: b.polynomial()
1/16*x^2 + 3*x + 1
}}}
On the other hand, I never thought that polynomial() was a good name...
