I think LSD radix sort is a valid alternative because it's stable, and
possibly a stable hybrid radix sort. Other possibilities are using sorting
networks instead of insertionsort for really small lists, and an algorithm
optimized for mostly sorted lists, but each of these has decreasing
marginal benefit. The idea with this library is that you don't need to
worry about the algorithm, it uses radix and/or comparison based sorting as
best suits your problem.

The Perl script provides a basic benchmarking and parameter tuning

Do you have a specific use case you'd like to use another algorithm for?
