collection_aggregate library Collection

Utilities for aggregating and sorting collections.

This includes:

• Grouping a collection's elements such as Group.lists.
• Sorting a collection's elements such as Order.ascending.
• Splitting a collection into parts such as Split.window.

Most functions in this library produce a new collection rather than modify the collection in-place.

See sugar.collection for other non-aggregating collection utilities.
