I don't have a strategy, but I have branches in various states of readiness that attempt to refactor both the old and new assumptions to make their code simpler and to bring them closer together. Some of the things I did or tried to do: * Remove the cumbersome and confusing Assume() syntax. * Have old-style assumptions defined only for instances of Expr and, most importantly, not for Booleans. * Merge sympy.core.logic and sympy.logic.boolalg (mostly by removing the former). I'll try to refine some of this into pull requests in the next days. -- You received this message because you are subscribed to the Google Groups "sympy" group.
