Hi, I was wondering why the quantum stuff (new and old) uses implicit imports. Well, it turns out that 2.5 years ago we have pushed in a fix
https://github.com/sympy/sympy/commit/0d259619130f7610112ad1a87e85ed2fc1dd7b4f to make sure we test implicit imports in doctests and the new regular expression broke the usual tests and nobody has noticed anything. Oops. One has to be very careful with these RE expressions, in fact I think that the only way is to always have tests for them, otherwise one can never get it right. So I have put there tests for the RE expression itself and fixed SymPy to work again. Fortunately not many fixes were needed, just in quantum (took 30min of work roughly): https://github.com/sympy/sympy/pull/413 Aaron, I think that this should go into the release as well. If all is ok, just push it in. Thanks, Ondrej -- You received this message because you are subscribed to the Google Groups "sympy" group. To post to this group, send email to sympy@googlegroups.com.
