OTOH, "new-assump" is meant to be pushed into master at some point, though it needs to be polished (better doc, more tests, ...) and more stuff could be backported from "use-new-assump2", so that's probably what you should start from. Unfortunately, I don't think I'll have time to make "new-assump" ready for inclusion before mid-June, but don't hesitate to do it yourself if you want.
As for Predicates not having reached master yet, the branch "implement-Predicate" is up for review [http://code.google.com/p/sympy/issues/detail?id=1903], so could be pushed in soon. I think Ondrej's changes are premature: we certainly need to separate "static" type-checking (based on querying an object's class, e.g. using .is_Integer) from dynamic inference (invoking assumptions and the like, e.g. using .is_integer), and never use the latter inside object constructors but this should be done under the control of a working test suite, otherwise we risk having to reimplement half of sympy. -- You received this message because you are subscribed to the Google Groups "sympy" group.
