Alright, so I took Vinzent's old branch and made the most important things work over current master - see my local_assump branch [*]. I also added the hashing extensions for caching I described. Now only someone has to be daring enough to rewrite all the .is_foo properties and see how much breaks.
[*] There are a few test failures, but nothing unfixable. @Haz: Can you take a look if this implementation of caching is still amenable to the problems you described? There is a test in test_cache.py that you could take as a baseline. Even if we decide that assumptions should all be passed around explicitely, I think assumption injection is a good transition strategy. -- You received this message because you are subscribed to the Google Groups "sympy" group.
