(1) The comparison could incorrectly return True in some cases + (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality. + (2) The comparison raised an OverflowError for large integers, leading + to unpredictable exceptions when combining integers and complex objects + in sets or dicts. + +- Issue #8748: Fix comparisons between complex and integer objects. + These used to convert the integer object to a complex number before + doing the comparison, giving a potentially incorrect result when + that conversion involved precision loss. (Ex: 2**53+1 == + complex(2**53) returned True; now returns False.) + - Issue #8766: Initialize _warnings module before importing the first module.
