Comment:
I should comment that it's actually not too hard to understand why this
still isn't fast enough to beat the code on #3436. A large part of the
problem is that we still represent elements of number fields by NTL
polynomials -- the lion's share of the difference comes down to the fact
that we end up doing several copies of data back and forth between NTL
`ZZX` objects and GMP/MPIR `mpz_t` and `mpq_t` objects, which adds up
fast.
