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 <some prefix>/Lib that have isinstance(<something>, int) in them? Or would you like to rephrase that with suitable qualifications? ;-)
I did not mean to sound like I was lecturing you personally.
Without taking a peek at the source, I would guess that the various uses of isinstance(<something>, int) are bugs, possibly replacing previous uses of type(<something>) is int, shortly after int subclassing was allowed. But that's just a guess.
