Maybe the best we can do is to set up a page on SymPy's wiki to propose an efficient API to replace the current one. I would like to see more of expression manipulation capabilities in SymPy, maybe resembling those of Wolfram Mathematica. I think that a good starting point would be to look at their API: http://reference.wolfram.com/mathematica/guide/Patterns.html In any case, I don't find myself comfortable with SymPy's idea of a mathematically-aware pattern matcher, it ends up to have a very ambiguous behaviour with an ill-defined attempt set of substitutions. Pattern matchers should be structural, with conditionals and optional wilds to give more advanced mathematical matchers. -- You received this message because you are subscribed to the Google Groups "sympy" group.
