Iterators vs. Cursors: A Case Study in Objects vs. Values

[John Rose]

I've been talking for a long time about using value classes
for representing cursor-like data, where part of the value
is constant (like a base address) and part is variable
(like an index).  I decided to write up a case study about
value-based cursors as a replacement to iterators, as
well as with some reflections on how this fits into the
larger schemes of Valhalla.

Enjoy!
