I'm not sure either.
I wonder if an algebra package would make sense or not. If so, it could contain the Field
top interfaces as well as field polynomials, Z/pZ, rational functions and BigReal. If such
an algebra were created I think polynomials should be moved there.
Polynomials (and rational functions) are at the boundary between algebra and analysis, at
least when using double coefficients only. When using Field coefficients, they are more algebratainted
to me.
What do other people think about this ?

I would really like to see 2.0 be published as soon as possible, but even my own tasks keep
being delayed (ODE for stiff equations, MATH172). I would like to target a release near end
of May.
