Comment:

 Currently pari conversion doesn't even work for series with integer
 coefficients.  This was pointed out in the docstring for
 `sage.modular.overconvergent.genus0.OverconvergentModularFormElement._pari_`.

 The attached patch extends the range of possible base rings significantly,
 but is still limited by what
 `sage.rings.polynomial.polynomial_element.Polynomial._pari_` can do; see
 its extensive docstring.
