Hi, It is great to see more discussion on the assumptions system. I do have a practical question. I am starting to work on a general quantum mechanics module for sympy with a few other people and we definitely need something *like* assumptions.
* Which assumptions system should I start out using? * Are there good docs on the new assumptions system? * Are the new assumptions system in trunk (even if most things don't use them)?
