The patch I just submitted change the operator module so that all
"predicates" are changed from returning 0 or 1 to returning False or
True.  This includes operator.truth().

IMO, truth() was intended to "normalize" a Boolean result into two
values that clearly stand for truth and falsehood; I don't see a
problem with the change.
