Are you just lecturing me personally (in which case off list would be more appropriate), or do you include the authors of the 17 files I count under /Lib that have isinstance(, int) in them? Josiah is correct, and those modules all have bugs. It seems I stand incontestably corrected. Sorry, both ways ;-/ Perhaps I missed a py3k assumption in this thread (where I see in the PEP that "Remove distinction between int and long types" is core item number one)? I googled, but could not find that isinstance(,int) was slated for deprecation, so I assumed that Josiah's absolute statement "1. ..." (above) could not be absolutely true, at least in the "has" (present) tense that he used. Is PEP 237 phase C to be implemented sooner than py3k, making isinstance(, int) a transparently distinction-hiding alias for isinstance(, integer), or outright illegal? IOW, will isinstance(, int) be guaranteed to be a bug, thus requiring code change? If so, when?
