Hmm, have there been API changes recently? With your branch, I'm not able to check an Equality expression for the attribute is_Relational:
*>>> from sympy import ** *>>> from sympy.abc import x, y* *>>> Eq(x, y).is_Relational* *Traceback (most recent call last):* * File "<stdin>", line 1, in <module>* *AttributeError: 'Equality' object has no attribute 'is_Relational'* *>>> * -- You received this message because you are subscribed to the Google Groups "sympy" group.
