Comment (by zimmerma):
I tried the patch on top of Sage 5.3 and got:
{{{
sage: R.<p,q,t> = ZZ[]
sage: poly = p+q^2+t^3
sage: poly = poly.polynomial(t)[0]
sage: poly
q^2 + p
sage: poly.degree(p)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
/tmp/<ipython console> in <module>()
/usr/local/sage-5.3/sage/local/lib/python2.7/site-
packages/sage/rings/polynomial/multi_polynomial_libsingular.so in
sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular.degree
(sage/rings/polynomial/multi_polynomial_libsingular.cpp:17832)()
TypeError: argument must canonically coerce to parent
}}}
Is that normal?
