-// Design:
-// - Original design was boost::chain in RangeEx (later joined)
-// - ER modified as follows:
-//     - sets the underlying iterator's Reference to one which both inputs are
-//     convertible to, and is lvalue-preserving
-// - Finally, MPG proposed a way to compose chains http://gist.github.com/287791
