“Applying functional programming in code design"

on YouTube ↗49m

" summary

Argues C++ can be structured functionally by preferring pure functions, using functional data structures (node‑based immutable lists that share nodes to cut memory), and designing value‑semantic, composable, lazy pipelines instead of mutating algorithms. Notes constexpr and a compiler pure attribute (GCC, Clang, ICC) and critiques the 2013 Walter Brown exception proposal and futures do_then error handling. Presents a small example application that composes lazy transforms, demonstrates node sharing, and proves the approach practical.
