by wrapping it?
Of course, but that will not give us "lattices of compatible finite
fields".
The way I see it, we should get the following tickets merged in that
order:
* #8335 David Roe's for lattices using (pseudo) Conway polynomials, this
only goes up and is obviously inefficient for large fields,
* #11938 which implements going down for finite field using Givaro,
* maybe extend it to all fields using pseudo-Conway polynomials in a
follow-up ticket,
* #13214 by Xavier Caruso, not sure how useful that will be, but that can
give a nice code basis to start upon,
* this ticket to implement general lattices of compatible finite fields.
