integration and long specification design.
Not quite; I am not at all advocating long specification design, and quick
integration of new features (which I am all for) is in fact easier if they
are smaller and don't intrude in places where they don't have to.
> Having some kind of support for lattices of finite fields has been a
long standing request. I agree with pbruin that a better interface between
generic finite fields and their actual implementation would be beneficial.
But this ticket is ready for review, while pbruin's is not.
The part that is relevant for this ticket is now ready for review: see
#14832 and #14833.
> Would it be that hard to adapt pbruin's or any other interface if this
ticket is merged? I'm willing to give positive review to this ticket, if
it stands some more testing, and it doesn't mess too much with #12142.
I am actually in favour of quickly solving the main things that this
ticket does (implementing pseudo-Conway polynomials and coercion between
different finite fields). I just think it shouldn't add more code to the
finite fields implementations (Givaro, PARI etc.), and should not (or at
least not yet) fix a meaning for `GF(p^n)`.
