summary
Argues for classifying code as actions, calculations and data and shows concrete C++ patterns that realize that — using ranges and views, lambdas, copy_if/transform/accumulate/reduce and call_once to turn temporaries into lazy pipelines, reduce allocations and make calculations thread‑safer. Demonstrates wrapping a C oven API with a lambda that captures a handle to give RAII via lambdas, composes filters/maps/reduces for the banana processor and birthday-card example, and emphasizes lazy evaluation and when copying versus mutating matters.
