This package provides linear time sorting, partitioning, and joins for a wide array of Haskell data types. This work is based on a "final encoding" of the ideas presented in multiple papers and talks by Fritz Henglein.
By adopting a final encoding we can enjoy many instances for standard classes, lawfully, without quotienting.
Contributions and bug reports are welcome!

groupingis now much more efficient.
groupingis now productive. This means it can start spitting out results as it goes! To do this I created the
promisespackage and switched to using it behind the scenes for many combinators that consume a
Group. This has a bunch of knock-on effects:
groupingis now working properly with respect to its law!
groupingnow uses an American-flag style top-down radix sort rather than a bottom up radix sort for all operations. This is sadly required for productivity. This will use a lot more memory for intermediate arrays, as we don't get to return them to storage after we're done. * We now use much smaller intermediate arrays for
grouping. Should we do the same for
