Comment #26 on issue 1026 by renato.c...@gmail.com: pypy doesn't run sympy http://code.google.com/p/sympy/issues/detail?id=1026
Inspecting Piecewise more closely, I think there are a lot of features that are missing. For instance, denesting Piecewise inside another Piecewise, simplification of redundant test cases, and advanced comparison (mutually excludent test cases will result in the same function, even if they appear in a different order).
All of those are needed for a solution that could work "in all cases", and it may not be so trivial to implement. So I think we should open a new issue for these features, and only fix the test for now (comparing to both possibilities, in this case).
