Well I prefer the Py3 behaviour.
I guess most people do, but I don't care for it. If I have an integer, I need to use // to divide, or it gets converted to a float. If I have a Fraction, I need to use /, or it gets converted to an integer. You say, "but // always produces an integer, that's so much easier." But I don't see why there has to be a special operator devoted to integers.
>>> from fractions import Fraction
>>> x = Fraction(22,7)
>>> y = 3
22/7 11/7 1
3 1.5 1

To be spotted easily?
Look your explanation was better than mine, you're far more experienced than me with python, nevertheless you didn't see the error in the code.
Wasn't explicit is better than implicit a python slogan?
Anyway I like the many operators in Perl, what's lacking is optional explicit typing, to tune inner loops.
Strangely the parser already allows typing, for many years yet.
