I don't know about the internal representations in python, but I
believe ints can be larger than ints. Nevertheless your example there
which would have drove me nuts if I found it :-). I like the true
division feature, but I find it too far deviant, if all of a sudden
code started producing floats instead of ints, on a given upgrade of
python someday soon.

I think the result should be int if it is an int, but float if and
only if it is really needed.

I think your right, this conversation should probably move to python
ideas, since this was by design and not a bug. (but I do not really
like this part of the "feature").
