Paraphrased, taking into account amendments:
* Perhaps rename groupBy to chunkBy. People coming from SQL and other
languages might expect groupBy to do hash-based grouping.
* The unary function implementation must return for each group a tuple
consisting of the key and the lazy range of values. The binary function
implementation should continue to only return the lazy range of values.
* SortedRange should add a method called groupBy(). Invoked with no
predicate, groupBy() should do what chunkBy does, using the sorting predicate.
* aggregate() should be removed until we figure out how best to integrate.
