Infer the truth value for an Instance. The truth value of an instance is determined by these conditions: * if it implements __bool__ on Python 3 or __nonzero__ on Python 2, then its bool value will be determined by calling this special method and checking its result. * when this method is not defined, __len__() is called, if it is defined, and the object is considered true if its result is nonzero. If a class defines neither __len__() nor __bool__(), all its instances are considered true.
