Description

If an input collection has a total ordering defined over its elements, what would be the best way of doing things like, for example, given two such collections producing for each element in the second collection a pair of itself and the closest element in the first collection (a consequence of this is that elements of the first collection may appear in multiple pairs in the output collection). Is that even remotely near what this library is designed for? What about being able to perform "scan"-like operations over ranges in the input data?

Research direction

No files, tests, or entry points are named. Start by reading the library's collection APIs and documentation to determine whether ordered inputs, nearest-element matching, and range scans are supported. Done would require a settled design and clearly specified semantics for these operations.
