Hello sympy-folk,
I just pulled a fresh master and then did a git rebase on one of my
branches. After I did the rebase, I ran the tests and got a few failures.
I'm running Python 2.6.2 on Mac OS X. They all seemed to be related to
ordered_iter. Is this a problem on my end or something bad in master? Output
below:
