New issue 2765 by [email protected]: Research ways to do the assumptions
system, including removing the old system
http://code.google.com/p/sympy/issues/detail?id=2765
See https://github.com/sympy/sympy/wiki/Assumptions and some threads on the
mailing list, as well as any issue with the Assumptions label. We have two
assumptions systems in SymPy, the old system, which works like
x = Symbol('x', positive=True)
x.is_positive
True
and the new system, which works like
ask(Q.positive(x), Q.positive(x))
True
