Feel free to add new items, or add comments to the existing ones. It would also be great if you could try the pynac symbolics with coefficients from domains with characteristic > 0. GiNaC makes some assumptions about the coefficients to take shortcuts in arithmetic. Since William added the capability to use sage objects as coefficients, these assumptions don't hold anymore. I fixed a few bugs related to this before the 3.2.alpha0, but it's very likely that there are many others waiting to be found.
