New issue 2346 by ronan.l...@gmail.com: Symbols should only be equal if
they have the same assumptions
http://code.google.com/p/sympy/issues/detail?id=2346
The problem is described in
http://code.google.com/p/sympy/issues/detail?id=2343#c3
Basically, if x1 = Symbol('x') and x2 = Symbol('x', positive=True), x1 ==
x2 but hash(x1) != hash(x2), which causes all sorts of trouble.
