Comment (by benjaminfjones):
Some additional notes regarding your comments, @kcrisman:
- The doctest of `desolve` that was failing was returning unconverted
Maxima output, that's what the `bessel_j`, etc are. With the v5 patch we
now have an honest Sage symbolic function as the return value in that case
(also, see the diff eq doctest examples I wrote).
- I changes from using \alpha as the order to \nu for consistency with
mpmath and Maxima.
- I changed the random expression seed to 53 (my favorite random integer)
and that test no longer raises an exception.
