I'd be wary of changing this sort of thing without a really good reason.
For our purposes, bugs in Python or operating systems or whatever never
really go away. There's always going to be someone out there running
Win98 with Python 2.6.0, and the cost of messing up their day outweighs
the benefit of tidying up the code.

Mathematics is the supreme nostalgia of our time.
