Comment #6 on issue 2738 by [email protected]: Make a distinction between operations and their result
http://code.google.com/p/sympy/issues/detail?id=2738
Another thing to consider is the ordering of args (for commutative operations). Should x + y and y + x be automatically canonicalized to one of the two? And if not, should they compare equal? My opinion at this point is that they should retain the input arg ordering, but I'm not sure about comparison (it depends on how structural vs. mathematical we want these objects to be).
