I was unaware that Python 3 removed the distinction between int (which used to be C-style int) and long (which was arbitrary precision).
If it's really idiomatic Python 3 to always use arbitrary precision integers for everything, then it's not really Julia's fault that Python 3 makes it more difficult to use performant arithmetic.
