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(<something>,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(<something>, int) a transparently distinction-hiding alias for
isinstance(<something>, integer), or outright illegal? IOW, will isinstance(<something>, int)
be _guaranteed_ to be a bug, thus requiring code change? If so, when?
