Ondrej, When I run test_type_a.py on my computer, it is passing without the error that you get. When I apply the patch:
def __call__(self, *args): c = args[0] + print c c = list(c) for me, it does just print out A3 or A4, it does not print out anything else. This is my output from the tests: sympy/liealgebras/tests/test_type_a.py[1] A3 Do you know why it would work for me on my computer, but not for you?
