What's in this library?

Stateful transducers and streaming-preserving group operations for the folds in Gabriel Gonzalez's foldl package.

When to use this library?

Why use this library for grouping instead of pipes-group?

Grouping fold-side instead of producer-side has the advantage that, since the results are still Folds, you can combine them using Applicative.

Also, Folds can work with sources other than Producers from pipes.

Grouping fold-side has limitations as well:
