Feature request: sorting a list slice

It would be useful if list.sort() accepted two more optional parameters, start and stop, so that you can sort a slice in place. In other words, x = range(100) x.sort(start=3, stop=-1) would be equivalent to x[3:-1] = sorted(x[3:-1]) but more efficient and without repeating the slice twice.
