Your advice is appreciated, but it would be helpful if you actually took the time to look at what SymPy does, instead of just ranting blindly. It feels like more often than not you mention some "mistake" that SymPy has already solved (this Karr convention is a nice example), in many cases a very long time ago. You yourself admitted that you've never actually used SymPy. I recommend giving it a try. You don't even need to install it. Just go to http://live.sympy.org/. Every time you say "SymPy is stupid because it doesn't consider X" when if fact we have already thought hard about X a long time ago and implemented what we saw as the best fit for it, you discredit yourself a little bit, because it's clear that you didn't even do any research as to what SymPy does.
