"""It would also be reasonable to assume that any sane language runtime would have integers transparently degrade to BIGNUMs, making the choice of accuracy over speed, but of course that almost never happens...""" Python 2 did this, but Python 3 doesn't. Does this mean that: 1) The performance advantage of native integers is negligible? 2) The performance benefit of having two representations for integers isn't worth the complexity of one data type having two representations? 3) The advantage of merging the types was so great that it was done in the most straight-forward way, and then nobody got around to doing performance testing? 4) Something else?
