The "tipical" sorting functions (as those in std.algorithm)
expect their input to be a RandomAccessRange, while slists and
dlists are, by definition, ForwardRanges and BidirectionalRanges
respectively. So I'm afraid there's no standard function to order
them out-of-the-box.
That's a limitation of many languages (e.g. C++ sort requires a
RandomIterator, which forward_list and list do not provide).
What's the best workaround depends on your exact use case.
