New description:
I would like to use the fraction field of infinite polynomial ring.
{{{
sage: X.<x,y> = InfinitePolynomialRing(QQ, implementation='sparse')
sage: z=R(x[1])
sage: 1/z
}}}
So far, one gets
{{{
NotImplementedError: Fraction Fields of Infinite Polynomial Rings are not
implemented
}}}
This seems to be a coercion problem.
