But why bother? The 2to3 converter can do this for you.
In a sense using range() is more likely to produce broken results in
3.0: if your code depends on the fact that range() returns a list, it
is broken in 3.0, and 2to3 cannot help you here. But if you use
list(xrange()) today, the converter will turn this into list(range())
in 3.0 and that will continue to work correctly.
