Hi:

I'm wondering if the following is correct behavior:

sage: x,y=PolynomialRing(QQ,2,"xy").gens()
sage: f = 5*x+y-5
sage: f(1,1)
 1
sage: type(f(1,1))
 <type 
'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'>

I usually think of the values of a polynomial as belonging to the
ground ring as opposed to the polynomial ring.
