Comment (by SimonKing):
First question: Why is this operation using the singular pexpect
interface, and not libsingular?
Second question: Why is `a._singular_init_()` returning `"a"` and not
`"poly(a)"` or so? As a result, we have
{{{
sage: M = PolynomialRing(QQ['a'].fraction_field(), ['x','y'])
sage: x,y = M.gens()
sage: a = M(M.base_ring().gen())
sage: singular(a).typeof()
number
sage: singular("a").typeof()
number
sage: singular("poly(a)").typeof()
poly
}}}
