Comment #18 on issue 1358 by wflynny: (e*f*e*f).subs(e*f,f*e+h) fails if e*f is not commutative http://code.google.com/p/sympy/issues/detail?id=1358
I can't seem to be able to run those tests correctly despite reading the tutorial. Could you please tell me where bin/test is? I wrote the following patch and test for mul.py. It's very cumbersome and there is still one large problem: division with substitution of more than 1 symbol in the denominator. Still haven't quite figured that out yet. Anyway, thought it would be nice to update.
