I don't think this is the desired behavior.

In [3]: a=Symbol('a')

In [4]: bool(And(2>a, a>2))
Out[4]: True

The `And` does not simplify, and the bool() conversion turns it into a Pythonic `True`.

The former happens because assumptions don't know about relations (yet), see "Remarks" in http://docs.sympy.org/latest/modules/assumptions/ask.html .

The latter happens because Python is converting an `And` object to `bool`, and since it's none of the objects that convert to `False`, it turns it into a `True`.
