Ranges for the Standard Library
summary
Demonstrates a concrete library (range-v3) and a working console calendar built by composing lazy views and eager actions, including a custom chunk/interleave/transpose trio that turns a range of dates into side‑by‑side months. Shows this composes without mutable state or explicit loops (one if only), uses Boost.DateTime and Boost.Format for IO, and highlights proposals for Concepts, range algorithms, sentinels and a TS toward stl2 — the example compiles and runs and the adapters are reusable.
