Comment #86 on issue 1598 by asmeurer: New polynomials manipulation module
http://code.google.com/p/sympy/issues/detail?id=1598
The same problem exists in master. RootOf is a mess. Consider the
finagling necessary to test it with dsolve()
in test_nth_linear_constant_coeff_homogeneous_RootOf() and @XFAIL
test_nth_linear_constant_coeff_homogeneous_RootOf_sol() (no doubt you have,
because this is exactly where
this ode comes from :).
If you can clean up RootOf to work like a normal SymPy object (i.e., not
have Poly in the .args, which messes up
things that expect sympified things in args), then it will become much more
useful.
