Comment:
The attached patch provides the basic skeleton for the proposed new
implementation. The following already works with the attached patch:
{{{
#!python
sage: from sage.rings.polynomial.polynomial_rational_flint import
Polynomial_rational_dense_flint
sage: P.<t> = QQ[]
sage: a = Polynomial_rational_dense_flint(P,1/2)
sage: b = Polynomial_rational_dense_flint(P,2/1)
sage: t = Polynomial_rational_dense_flint(P,is_gen=True)
sage: a*t
1/2*t
sage: a*t*b
t
sage: a*t*b*b
2*t
sage: a*t*b*(b*t)
2*t^2
sage: a*t*b*(b*t)*a
t^2
}}}
